        * wtf/text/StringBuilder.cpp:
        (WTF::appendQuotedJSONStringInternal):
        The cases '"' and '\\' are not that uncommon, and they can easily
        be handled in the original branch testing for them.

        This is about 2.5% better on the JSON.stringify test.

        REGRESSION (bmalloc): WebKit performance tests don't report memory stats.

        Meanwhile a better way of getting memory stats with bmalloc is not found
        (see bug 136592), we can report as memory stats the resident set size

        CheckedArithmetic's operator bool() and operator==() is broken.
        https://bugs.webkit.org/show_bug.cgi?id=146129

        Reviewed by Geoffrey Garen and Oliver Hunt.

        The existing operator UnspecifiedBoolType*() in CheckedArithmetic is erroneously
        allowing the Checked value to be implicitly casted into pointer types.  This is
        because it is doing a reinterpret_cast<UnspecifiedBoolType*>(1) whereas the idiom
        relies on the address of a member e.g. &Checked::m_value.  As a result,
        ImageBufferData::putData() was getting an implicit cast of a Checked value to
        (void*)1 and doing incorrect pointer comparisons on it.

        Also, 2 of CheckedArithmetic's operator==() will crash if used on an overflowed
        value, while a 3rd one does not.  The 3rd one should be consistent and also crash
        if used on an overflowed Checked value.

        In this fix, we replace operator UnspecifiedBoolType*() with an explicit operator
        bool().  We also add the missing operators <, <=, >, and >=.  That takes care of
        the comparisons in ImageBufferData::putData().

        [GLib] Move files under Source/WTF/wtf/gobject to Source/WTF/wtf/glib
        https://bugs.webkit.org/show_bug.cgi?id=145799

        Reviewed by Carlos Garcia Campos.

        Move the GLib-specific files to the Source/WTF/wtf/glib/ directory.
        'gobject' wasn't the most appropriate name for the directory since
        GObject is a submodule of GLib, but a lot of the code there didn't
        have much to do with GObject specifically.

        Build rules for the moved files are also updated.

        As the management of structure sets evolved in JSC, the StructureSet data structure grew
        increasingly smart. It's got some smart stuff for managing small sets of pointers. I
        wanted to take the generic logic out of JSC and put it into a reusable templatized class

        Introduce UniquedStringImpl and SymbolImpl to separate symbolic strings from AtomicStringImpl
        https://bugs.webkit.org/show_bug.cgi?id=144848

        Reviewed by Darin Adler.

        he current AtomicStringImpl accidentally means the symbol OR atomic StringImpl.
        t's not correct to its name and it's error prone.

        In this patch, we'll introduce/changes classes into WTF.

        1. UniquedStringImpl
        It's derived class from StringImpl. And it represents symbol || atomic StringImpl.

        2. SymbolImpl
        It's derived class from UniquedStringImpl. Only symbol strings can become this.
        It ensures the given StringImpl is symbol in compile time.

        3. AtomicStringImpl
        It's derived class from UniquedStringImpl. Only atomic (non-normal && non-symbol) strings can become this.
        It ensures the given StringImpl is atomic in compile time.

        And, in this time, I just accept UniqueStringImpl in AtomicString. As the result,
        1. Now AtomicStringImpl issue is fixed. Its SymbolImpl is separated and UniquedStringImpl is introduced.
        2. But AtomicString still have both symbol and atomic strings.
        This should be solved in the separated patch.

       Ensure that all the smart pointer types in WTF clear their pointer before deref
       https://bugs.webkit.org/show_bug.cgi?id=143789

       Reviewed by Ryosuke Niwa.

       In order to prevent use after free bugs caused by destructors
       that end up trying to access the smart pointer itself, we should
       make sure we always clear the m_ptr field before calling deref.

       Essentially the UaF path is:
       struct Foo : RefCounted<Foo> {
         Wibble* m_wibble;
         void doSomething();
         ~Foo() { m_wibble->doSomethingLikeCleanup(); }
       };

       struct Wibble {
         void doSomethingLikeCleanup()
         {
           if (m_foo) {
               /* if this branch is not here we get a null deref */
               m_foo->doSomething();
           }
         }
         void replaceFoo(Foo* foo) { m_foo = foo; }
         RefPtr<Foo> m_foo;
       };

       Wibble* someWibble = /* a Wibble with m_foo->m_refCount == 1 */;
                            /* and m_foo points to someWibble       */;

       someWibble->replaceFoo(someOtherFoo);
       + someWibble->m_foo->m_ptr->deref();
         + someWibble->m_foo->m_ptr->~Foo()
           + someWibble->m_foo->m_ptr->m_wibble->doSomethingLikeCleanup()
             + someWibble->m_foo->m_ptr->m_wibble /* someWibble */ ->m_foo->m_ptr /*logically dead*/ ->doSomething()

       By clearing m_ptr first we either force a null pointer deref or
       we force our code down a path that does not use the dead smart
       pointer.

        Do not keep a reference of the WorkQueue for the entire life of
        its worker thread, since every task scheduled on the WorkQueue
        already takes a reference. Instead, take a reference of the main

        loop hasn't been released to avoid runtime warnings (see
        webkit.org/b/140998). Also removed the g_main_context_pop_thread_default()
        from the thread body, since the thread-specific context queue will
        be freed anyway when the thread exits.
        If the WorkQueue is released early, before the thread has started,
        schedule a main loop quit in the context, to make sure it will
        be the first thing run by the main loop and the thread will exit.

        Optimize serialization of quoted JSON strings.
        <https://webkit.org/b/144754>

        Reviewed by Darin Adler.

        Add a StringBuilder API for appending a quoted JSON string. This is used by
        JSON.stringify() to implement efficient appending of strings while escaping
        quotes, control characters and \uNNNN-style characters.

        The main benefit comes from only doing a single buffer expansion up front,
        instead of doing it every time we append something. The fudge factor is pretty
        large, since the maximum number of output characters per input character is 6.

        The first landing of this patch had two bugs in it:

        - Made \uNNNN escapes uppercase hexadecimal instead of lowercase.
        - Didn't preallocate enough space for 8-bit input strings.

        Both were caught by existing tests on our bots, and both were due to last-minute
        changes before landing. :/

        Reviewed by Geoffrey Garen.

        When we register symbolized StringImpl* into SymbolRegistry, symbolized StringImpl* is aware of that.
        And when destructing it, it removes its reference from SymbolRegistry as if atomic StringImpl do so with AtomicStringTable.
        While AtomicStringTable (in WebCore case) exists in thread local storage,
        SymbolRegistry exists per VM and StringImpl* has a reference to the registered SymbolRegistry.

        Since StringImpl has isSymbol etc. members, it's class is aware of Symbol use cases.
        So introduce SymbolRegistry in WTF layers as if AtomicStringTable.

        Replace TCSpinLock with a new WTF::SpinLock based on WTF::Atomic.
        <https://webkit.org/b/142674>

        Reviewed by Filip Pizlo.

        We no longer use TCMalloc in our code, and we now have C++11.  This replaces the
        TCMalloc_SpinLock with a new WTF::SpinLock based on WTF::Atomic (which is a
        wrapper around std::atomic).

        Note that there is a StaticSpinLock and a SpinLock:

        1. StaticSpinLock is an alias for SpinLockBase, and its initialization relies on
           static / global std:atomic being automatically initialized to 0 at compile time.
           Hence, StaticSpinLock should only be used for statics / globals (including
           static members of classes / structs).

        2. SpinLock is derived from SpinLockBase, and adds a default constructor to
           initialize its internal atomic value to 0.  Because SpinLock has a constructor,
           it cannot be used for statics / globals.  Objects that want to embed a spin
           lock as an instance field should use SpinLock so that it is initialized properly.
           std::atomic will not automatically initialize instance fields to 0.  Hence,
           StaticSpinLock will not work correctly as instance fields of a class / struct.

        Introduce WTF::Atomic to wrap std::atomic for a friendlier CAS.
        <https://webkit.org/b/142661>

        Reviewed by Filip Pizlo.

        The CAS functions provided by std::atomic takes a reference to the expected
        value and modifies it if the CAS fails.  However, in a lot of our CAS usage,
        we don't want the expected value to change.  The solution to this is to
        provide a WTF::Atomic struct that wraps std::atomic, and provide CAS
        methods that won't alter the expected value if the CAS fails.

        The method names in WTF::Atomic are chosen to be identical to those
        in std::atomic so that WTF::Atomic can be a simple drop in replacement
        for std::atomic.

        8-bit version of weakCompareAndSwap() can cause an infinite loop.
        https://webkit.org/b/142513>

        Reviewed by Filip Pizlo.

        Presently, Bitmap::concurrentTestAndSet() uses the 8-bit version of
        weakCompareAndSwap() (which compares and swaps an uint8_t value).
        Bitmap::concurrentTestAndSet() has a loop that checks if a bit in the
        byte of interest has been set.  If not, it will call the 8-bit CAS
        function to set the bit.

        Under the covers, for ARM, the 8-bit CAS function actually works with a
        32-bit CAS.  The 8-bit CAS will first fetch the 32-bit value in memory
        that should contain the 8-bit value, and check if it contains the
        expected byte.  If the value in memory doesn't have the expected byte,
        it will return early to its caller.  The expectation is that the caller
        will reload the byte from memory and call the 8-bit CAS again.

        Unfortunately, this code path that returns early does not have a
        compiler fence.  Without a compiler fence, the C++ compiler can
        optimize away the reloading of the expected byte value, leaving it
        unchanged.  As a result, we'll have a infinite loop here that checks a
        value that will never change, and the loop will not terminate until the
        value changes.

        The fix is to eliminate the early return check in the 8-bit CAS, and
        have it always call down to the 32-bit CAS.  The 32-bit CAS has a
        compiler fence which will prevent this issue.

        Regression(r173761): ASSERTION FAILED: !is8Bit() in StringImpl::characters16()

        Fix ASSERTION FAILED: !is8Bit() in StringImpl::characters16() from
        WTF::equalInner() after r173761. The code was incorrectly assuming that
        if stringImpl is 16-bit, then matchString is 16-bit too, which is not
        correct.

        Also rename WTFString::startsWith() / endsWith() taking an offset to
        hasInfixStartingAt() / hasInfixEndingAt() for clarity. It seems odd
        to call it startsWith even though it won't technically *start* with
        the pattern if the input offset is greater than zero.

        WeakPtr functions crash when created with default constructor
        https://bugs.webkit.org/show_bug.cgi?id=140479

        Reviewed by Andreas Kling.

        This patch rearranges how WeakPtr works, and has the following ideas behind it:

        1. WeakPtr should use Ref internally. This solves the crash by always having a
        valid WeakReference.
        2. Clients should not be able to construct WeakReferences directly. Instead,
        only WeakPtrFactory (and WeakPtr's default constructor) should be able to
        construct them. They are considered an implementation detail of WeakPtr.
        3. Except for the default constructor, clients should not be able to construct
        WeakPtrs directly. Instead, the WeakPtrFactory must construct them. This
        guarantees that the WeakPtrs all reference the same WeakReference.
        4. Clients can construct a WeakPtr using its default constructor, and then
        use the assignment operator to make it non-null. (Or they could use
        WeakPtrFactory to make it non-null at creation-time.)
        5. No one was using WeakReference::bindTo(), and it doesn't seem useful, so I
        removed it.

        (WTF::Ref::Ref): Added extra ASSERT()s, and explicitly deleted copy

        RefPtr does). These constructors/operators are relied upon in various places
        throughout WebCore.

        std::all_of requires complete C++ iterators in GCC 4.8

        In the WebKit2/UIProcess/WebProcessLifetimeObserver.cpp, std::all_of
        is used for HashIterators. However, std::all_of requires the complete

        it raises compile error in GCC 4.8 (and libstdc++) environment.

        This patch inherits std::iterator with appropriate type parameters.

        Update the WTF::Optional implementation to use std::aligned_memory and

        Currently all token vended by a RefCounter have the same type - Ref<RefCounter::Count>.
        This means there is no compile time type checking to prevent mistakes. Update the count()
        method to token<>(), templated on type used to identify the token being returned.
        Calls to token<T>() will return a result of type RefCounter::Token<T>.

        There are a few problems with the fact the counter will return you an exact count of the
        number of outstanding tokens:
          - It is desirable to only fire the callback on zero-edge changes; it is more consistent
            to do so if the value is only readable as a boolean.
          - It is desirable to provide the value as an argument to the callback, however to make
            this useful for integer values it is also necessary to indicate the direction of change
            (0->1 is often interesting where 2->1 is not).
          - There is a mismatch between the precision of returning a count, and the inherent
            imprecision of a token based mechanism, where it may be difficult to guarantee
            absolutely no unnecessary refcount churn, and thus unintentional counter values.

        Reviewed by Mark Lam.

        Add a new IndexedIterator struct to WTF that wraps a
        Vector type and index to provide pointer like semantics
        while still performing runtime bounds checking, even in
        release builds. We store a simple index into the vector
        which means that this iterator allows vector resizing
        during iteration. If the vector is resized such that the
        iterator is out of bounds, then any attempt to dereference
        the iterator will crash safely.

        For the purpose of retaining semantically equivalent
        behaviour, the iterator can be moved to m_index == size()
        as that is the standard "end" terminator for these types.
        Attempting to dereference at that point will still crash
        rather than perform an unsafe memory operation.

        By necessity there are many overrides for operator + and - as
        we otherwise hit many different type promotion ambiguities when
        performing arithmetic with iterators. These ambiguities are also
        different for 32- vs. 64-bit, so duplicating the functions
        and then forwarding to the core implementations that performed
        the bounds checking and mutation seemed like the right call.

        Replace PassRef with Ref/Ref&& across the board.
        <https://webkit.org/b/139587>

        Reviewed by Darin Adler.

        Kill the PassRef class and replace it by Ref/Ref&&.
        Usage is simple:

            - For locals and members, keep using Ref<T>.
            - For return types, use Ref<T>.
            - For (ownership-transferring) arguments, use Ref<T>&&.

        When passing to a Ref&&, use WTF::move() to mobilize the value
        at the call site, e.g:

            void myFunction(Ref<Foo>&&);

            Ref<Foo> myFoo(Foo::create());
            myFunction(WTF::move(myFoo));
            // 'myFoo' is invalid from this point forward.

        As you can see, it works a lot like PassRefPtr, but unlike PassRefPtr
        it won't surprise you by becoming null *unless* you WTF::move it.

        I've also added a Ref::copyRef() for instances where you want to
        return a Ref *without* transferring ownership, e.g code like:

            Ref<Foo> foo() { return m_foo; }

        ... now becomes ...

            Ref<Foo> foo() { return m_foo.copyRef(); }

        This makes it explicit that a refcount bump will occur.

        Finally, do note that unlike last year's PassRef, Ref&& does not
        require you to move it to avoid leaking; it will clean itself up.

        Generalize PageActivityAssertionToken
        https://bugs.webkit.org/show_bug.cgi?id=139106

        Reviewed by Sam Weinig.

        PageActivityAssertionToken is a RAII mechanism implementing a counter, used by PageThrottler
        to count user visible activity in progress on the page (currently page load and media playback).
        Use of an RAII type is prevents a number of possible errors, including double counting a single
        media element, or failing to decrement the count after a media element has been deallocated.

        The current implementation has a number of drawbacks that have been addressed by this refactoring:
         - specific to single use in PageThrottler class - not reusable.
         - incomplete encapsulation - the counter and WeakPtrFactory that comprise the current implementation
           are not encapsulated (are in the client type, PageThrottler).
         - tokens are not shared - PageActivityAssertionToken instances are managed by std::unique, every
           increment requires an object allocation.
         - redundancy - the current implementation uses a WeakPtr to safely reference the PageThrottler, this
           is internally implemented using a reference counted type, resulting in two counters being
           incremented (one in the PageActivityAssertionToken, one in the PageThrottler).

        In the reimplementation:
         - a callback is provided via a lambda function, which allows for easy reuse without a lot of
           boilerplate code.
         - the counter, callback and ownership of the otherwise weakly-owned token is encapsulated within the
           RefCounter type.
         - a single count within RefCounter::Count stores the counter value, and also manage the lifetime
           of this object.
         - standard RefPtrs are used to manage references to the RefCounter::Count.

        Make sure range based iteration of Vector<> still receives bounds checking
        https://bugs.webkit.org/show_bug.cgi?id=138821

        Reviewed by Mark Lam.

        Add a new IndexedIterator struct to WTF that wraps a
        Vector type and index to provide pointer like semantics
        while still performing runtime bounds checking, even in
        release builds. We store a simple index into the vector
        which means that this iterator allows vector resizing
        during iteration. If the vector is resized such that the
        iterator is out of bounds, then any attempt to dereference
        the iterator will crash safely. Any other errors, including
        overflows, and over extending the iterator will likewise
        crash.

        For the purpose of retaining semantically equivalent
        behaviour, the iterator can be moved to m_index == size()
        as that is the standard "end" terminator for these types.
        Attempting to dereference at that point will still crash
        rather than perform an unsafe memory operation.

        In order to maintain the validity of all the bounds checking,
        we perform full integer range checking prior to any mutation
        of the iterator location. If we detect an arithmetic overflow
        we will crash rather than attempting to carry on.

        By necessity there are many overrides for operator + and - as
        we otherwise hit many different type promotion ambiguities when
        performing arithmetic with iterators. These ambiguities are also
        different for 32- vs. 64-bit, so duplicating the functions
        and then forwarding to the core implementations that performed
        the bounds checking and mutation seemed like the right call.

        Update the Vector API to deal with unsigned types instead of size_t
        https://bugs.webkit.org/show_bug.cgi?id=138824

        Reviewed by Andreas Kling.

        Update part of the Vector API to deal with unsigned types instead of
        size_t. The Vector class is already using unsigned type for its
        capacity and size data members. However, the Vector API was never
        updated accordingly.

        The rest of the Vector API will be ported in follow-up patches to
        make the change smaller and more easily reviewable.

        Add a more correct way to compare floating point numbers and use it
        https://bugs.webkit.org/show_bug.cgi?id=138527

        Reviewed by Darin Adler.

        To compare floating point numbers in the code base, we would often rely
        on the following check:
        std::abs(a - b) <= std::numeric_limits<T>::epsilon()

        However, this is not correct for arbitrary floating point values, and
        will fail for values that are not close to zero.

        This patch introduces a WTF::areEssentiallyEqual() templated function
        that can only be called with floating point types and relies on the
        following formula from [1][2] that defines u as being "essentially
        equal" to v if: | u - v | / |u| <= e and | u - v | / |v| <= e

        Reviewed by Sergio Villar Senin.

        We made GMainLoopSource thread safe, but in most of the cases we
        know the sources are used by a single thread, which has an impact
        in the performance (mutex, GCancellable, etc.). The new class
        GThreadSafeMainLoopSource inherits from GMainLoopSource overriding
        the new virtual methods and calling the parent for the common code.
        GMutexLocker now supports recursive mutexes, it's a template that
        can wrap a GMutex or a GRecMutex. GThreadSafeMainLoopSource uses a
        recursive mutex using the new GMutexLocker API.

        This patch adds two functions, codePoints() and codeUnits(), on StringView.
        These two functions return small objects which have begin() and end() functions,
        which means it can be used by the modern for loop style. This small class also
        has an inner iterator class which can be incremented, dereferenced, and
        compared.

        Using these new objects looks like this:
        for (UChar codeunit : stringView.codeUnits()) { } and

        map.add(WTF::move(foo), Bar());

        1. It is more consistent with downcast<>(T*), which will succeed even

        2. It simplifies the code a bit as it gets rid of a lot of explicit

        Add support for having WTF::getPtr() transform reference arguments

        appropriate and so that the generated bindings code can handle this

        This patch had to alter the way getPtr() was overloaded for smart
        pointer types so that we don't call &p on smart pointers but p.get().
        This was needed because the new WTF::getPtr(T&) was being called for
        RefPtr<T> arguments instead of the getPtr(const RefPtr<T>&) overload.
        This was addressed using traits and template specialization to
        distinguish WTF smart pointers from other types.

        GMainLoopSource is exposed to race conditions
        https://bugs.webkit.org/show_bug.cgi?id=135800

        Reviewed by Carlos Garcia Campos.

        GMainLoopSource objects can be dispatching tasks on one thread
        while having a new task scheduled on a different thread. This
        can for instance occur in WebKitVideoSink, where the timeout
        callback can be called on main thread while at the same time
        it is being rescheduled on a different thread (created through
        GStreamer).

        The initial solution is to use GMutex to prevent parallel data
        access from different threads. In the future I plan to look at
        the possibility of creating thread-specific GMainLoopSource
        objects that wouldn't require the use of GMutex.

        GSource, GCancellable and std::function<> objects are now packed
        into an internal Context structure. Using the C++11 move semantics
        it's simple to, at the time of dispatch, move the current context
        out of the GMainLoopSource object in case the dispatch causes a
        rescheduling on that same object.

        Also added in the Context struct is a new GCancellable. The pointer
        of that object is shared with the GMainLoopSource before the Context
        is moved out for the callback dispatch. This makes it safe to cancel
        or even delete the GMainLoopSource during the dispatch and prevents
        use-after-delete on GMainLoopSource once the dispatch is done in
        the GMainLoopSource::*Callback() methods.

        All the schedule*() methods and the cancelWithoutLocking() method
        callers now lock the GMutex to ensure no one else is accessing the
        data at that moment. Similar goes for the dispatch methods, but those
        do the dispatch and possible destruction duties with the mutex unlocked.
        The dispatch can cause rescheduling on the same GMainLoopSource object,
        which must not be done with a locked mutex.

        GMainLoopSource is exposed to race conditions
        https://bugs.webkit.org/show_bug.cgi?id=135800

        Reviewed by Carlos Garcia Campos.

        GMainLoopSource objects can be dispatching tasks on one thread
        while having a new task scheduled on a different thread. This
        can for instance occur in WebKitVideoSink, where the timeout
        callback can be called on main thread while at the same time
        it is being rescheduled on a different thread (created through
        GStreamer).

        The initial solution is to use GMutex to prevent parallel data
        access from different threads. In the future I plan to add better
        assertions, some meaningful comments and look at the possibility
        of creating thread-specific GMainLoopSource objects that wouldn't
        require the use of GMutex.

        GSource, GCancellable and std::function<> objects are now packed
        into an internal Context structure. Using the C++11 move semantics
        it's simple to, at the time of dispatch, move the current context
        out of the GMainLoopSource object in case the dispatch causes a
        rescheduling on that same object.

        All the schedule*() methods and the cancelInternal() method callers
        now lock the GMutex to ensure no one else is accessing the data at
        that moment. Similar goes for the dispatch methods, but those do
        the dispatch and possible destruction duties with the mutex unlocked.
        The dispatch can cause rescheduling on the same GMainLoopSource object,
        which must not be done with a locked mutex.

        Fix handling of attributes prior to compiling shader
        https://bugs.webkit.org/show_bug.cgi?id=132430

        Reviewed by Dean Jackson.

        WebGL programs that called bindAttribLocations prior to compiling shader sources
        would perform the bind using the non-hashed symbol name, but would later create
        the attributes as hashed names. Consequently, the program would refer to
        attributes that were never actually part of any shader, resulting in some amazing
        display artifacts.

        This patch adds a dictionary of hashed symbol names so that we can tell the WebGL
        program the proper name that will be used when the shader is eventually compiled,
        allowing the WebGL program to link against the proper symbol after compiling and
        linking completes.

        (1) JSC API VMs each get their own string table, switch the string table on
            API entry/exit.

        [GLIB] Add GMainLoopSource class to wrap idle and timeout sources
        https://bugs.webkit.org/show_bug.cgi?id=130027

        Reviewed by Martin Robinson.

        GLib main loop sources like idle and timeouts are sometimes
        unconvenient to use and it's very common to forget canceling the
        source when the object is destroyed or reset the source ID in the
        callback when called. GMainLoopSource is a wrapper class to make it
        easier to handle sources and also to avoid those typical mistakes.
        It forces to create sources with a name and the user doesn't have
        to deal with the source ID anymore. The source is cancelled when
        the object is deleted or when a new source is scheduled. It uses
        std::function for callbacks so that we no longer need to use the
        "proxy" static callbacks either. We can use std::bind to use a
        function pointer or a member or even lambda functions. It also handles
        repeating sources automatically depending on whether the given
        function returns a bool or not.

        the scheduler is free to schedule whatever thread it wants.  By lowering the

        Remove ENABLE_GLOBAL_FASTMALLOC_NEW

        Reviewed by Geoffrey Garen.

        Remove the global operator new/operator delete overrides. Having ALWAYS_INLINE operators
        like we do is really undefined behavior according to the C++ standard and we've been lucky enough
        to get away with it so far, but any code that calls operator new/operator delete inside from the C++ standard
        library (not from headers that are included) will be mismatched and potentially crash. libc++ calls
        delete in it's std::thread implementation for example.
        
        The only supported way to override operator new and operator delete globally is to not use inline
        functions, but that would mean that any application using WebKit would not be able to provide custom
        operator new/operator delete functions so we'll just reuse the already existing infrastructure consisting
        of the WTF_MAKE_FAST_ALLOCATED macro.

        The const qualifiers for the return types of FilterIterator::operator*() and TransformIterator::operator*()

        Vector with inline capacity should work with non-PODs
        https://bugs.webkit.org/show_bug.cgi?id=128864

        Reviewed by Michael Saboff.
        
        Previously, we would copy the inline storage of a vector as if it was a bag of bits.
        This presumed that the element type was relocatable. In general this is only true for
        PODs.
        
        This patch changes this by introducing a swap operation over inline storage. This swap
        operation requires being told about the size that is in use.
        
        Deques would have required some cleverness to make this work, because the swap
        operation needs to know which subset of elements are in-use and assumes that a size is
        sufficient for this. That's not true for deques. Instead of trying to do very clever
        things, I just removed the inline capacity option from Deque. I believe that this is
        fine since there are only two users of Deque with inline capacity, and both of them
        appear to be allocated rarely enough that inline capacity probably doesn't help much.

        GUniqueOutPtr is a simplified version of GOwnPtr for the cases

        uses GUniquePtr to free the contained object and to release the
        container pointer. The API is very simple to make sure this is
        only used when outPtr() is needed. It can't be constructed with a
        pointer, and there's not method to set a new pointer. Another
        difference with the old GOwnPtr is that outPtr() can be used
        multiple times, because it frees any pointer previously set.

        The current stack limit computation assumes that the stack is allocated
        in high memory. On Windows, the stack seems to be allocated very near
        address 0, and is smaller in size than our Options::maxPerThreadStackUsage().
        This combination triggers a bug where StackBounds::recursionLimit()
        underflows and computes a limit address that is ridiculously high in memory.
        The net effect is that the Windows port thinks its out of stack space all
        the time.

        We now check for potential underflows in StackBounds and return an

        Reviewed by Alexey Proskuryakov.

        When WEB_THREAD is enabled, and callOnMainThread() is called from the main
        thread, if the web thread is locked, a timer is set and the passed-in function
        is called on the next run-loop. However, by that time the web thread may have
        been unlocked, and isMainThread() will no longer return true, resulting in
        an assert.

        Instead, scheduleDispatchFunctionsOnMainThread() should check isWebThread(),
        which is equivalent to isMainThread() when the WEB_THREAD is disabled, but
        will do the correct thing when WEB_THREAD is enabled.

        Reviewed by Gustavo Noronha Silva.

        The idea is to replace GOwnPtr with a template alias of
        std:unique_ptr. Not everything can be replaced, though, because
        GOwnPtr::outPtr() doesn't seem to be possible to implement with
        unique_ptr. This smart pointer is more flexible than GOwnPtr and
        allows to transfer the ownership of the pointer using

        g_variant_ref_sink calls g_variant_ref, so it's safe to use it always.

        Reviewed by Antti Koivisto.

        Add a new StringView class which is an immutable reference to either an 8-bit or a 16-bit string.

        This makes it easier to pass substrings around without having to either copy string data
        or upconvert and use UChar pointers.

        The StringView class is very loosely based on the std::string_view class which is proposed for a future version of C++,

        Refactor NSActivity handling code from ChildProcess to UserActivity
        https://bugs.webkit.org/show_bug.cgi?id=126330

        Reviewed by Sam Weinig.

        UserActivity is a mechanism to express to the operating system (where appropriate)
        that a user initiated activity is taking place, and as such that resources should be
        made available to the process accordingly.

        Currently we hold a single NSActivity, at the WebKit layer. This refactoring allows us
        to hold different activity tokens for different user actions (which simplifies the
        handling, and aides debugging since the token can more accurately express the activity
        taking place), and also will allow us to avoid the layering difficulty of calling back
        up the stack to WebKit to register that an activity is taking place.

        Reviewed by Michael Saboff.

        Found by code inspection.  If there is a collision in an Identifier
        table when comparing to a string literal we attempt to use the data
        pointer (essentially this ends up being a null termination check).

        Previously unique pointers just used the literal 1 as the data address
        but this obviously fails when dereferenced.  Instead we now make the
        data pointer point to the location of the buffer pointer itself.  As
        the buffer pointer is initialised to 0, this satisfies the requirement
        that the 0-length unique string is null terminated.

        RefPtr::releaseNonNull() incorrectly increments the refcount.

        Start passing RenderStyle around with PassRef.

        Added some new PassRef tricks to make this patch possible.

        * wtf/PassRef.h:
        (WTF::PassRef::get):

            Added a get() helper to facilitate writing functions that
            construct a new object and call some functions on it before
            returning it.

        (WTF::PassRef::dropRef):

            This will deref() the referenced object and mark the PassRef
            as "passed." This is used in code paths where the PassRef is
            going to go out of scope with nobody to take it over.

        (WTF::PassRef::leakRef):

            Renamed takeReference() to leakRef() and made it public so
            we don't have to awkwardly sink the PassRef into a Ref for
            e.g static locals.

        * wtf/RefPtr.h:
        (WTF::RefPtr::releaseNonNull):

            Added RefPtr::releaseNonNull() for a convenient way of creating
            a PassRef<T> from a RefPtr<T>. This function may only be called
            if the RefPtr is known to be non-null.
