4bab72368f glx: Do not flood with warnings when reducing during config lookup
With things like sample count reducing a format (16 -> 8 -> 4 -> ...)
and trying again is perfectly fine. There is no need to show warnings
in this case. Even some of our own examples in qtdeclarative do a
setSamples(16) which is rarely supported. These all show warnings since
8ec98fc2dc. Avoid this.

5322998a0b Limit curve stroking threshold to reasonable range
Avoid unreasonable threshold values for extremely wide pens, since
that can lead to a very high processing cost.

The rare usecases where this would make a noticeable difference will
necessarily also be using scaling, and so is anyway depending on
setting a suitable curve threshold manually.

0b984e141b Bound the scope of QTRY_LOOP_IMPL()'s local variable
QTRY_IMPL() exercises QTRY_LOOP_IMPL() twice, once directly, the
second time via QTRY_TIMEOUT_DEBUG_IMPL(); and QTRY_LOOP_IMPL()
deliberately doesn't bound its scope (e.g. with the canonical
do{...}while(0) trick) so that the latter can access its local
variable. Unfortunately, this means the local's declaration in the
second use of QTRY_LOOP_IMPL() shadows the first. So enclose the first
in braces to bound the scope.

fcc5323a08 Make test less dependent on moving the cursor
The sendMouseMove() function calls QTest::mouseMove(),
which again calls QCursor::setPos() to move the cursor.
It then creates and sends a MouseMove event, using
the constructor which picks up the global position
by calling QCursor::pos().

On macOS 10.14, QCursor::setPos() may silently fail
if the user does not grant the application permission
to move the cursor (via a dialog). As result of this
the mouse move event gets an incorrect global position.

Provide the global position directly when creating
the event to make sure it gets the correct value.

79e0effead Fix crash in QTextDocument::clearUndoRedoStacks()
When calling QTextDocument::clearUndoRedoStacks() with UndoStack,
there were two bugs: The first was that we were retrieving
the item at "undoState" and deleting this. This is actually the
upper limit of the for loop. If the stack does not contain any
redos, then it would be == undoStack.size() and we would assert.

If there were redos, then we would delete the item at undoState
multiple times (actually undoState times).

In addition, when the loop exited, we first removed the dangling
pointers using remove() and then there was a weird resize() to
the new size minus the old undoState.

This would either assert because we tried to resize to a negative
number, or it would arbitrarily remove items from the stack.

QTextDocument::clearUndoRedoStacks(QTextDocument::UndoStack).

1880fba971 Android: Fix QMenu on 64 bit
The platform menu tags in Qt are actually the pointers, so they are
64-bit values when the build is 64 bit. Since menu IDs in Android
are 32-bit ints, we cannot cast back and forth like we do. To fix
this, we add a separate hash of menu IDs to allow mapping between
Java and C++. For easier book-keeping, we add the hashes to the
menu bar and menu classes, so that we can easily recycle old menu
IDs when they are no longer in use.

Note that overriding the tag on the menus by calling setTag() will
not work, since Qt Widgets will later override it again by setting
it back to the menu's pointer.

[ChangeLog][Android] Fixed an issue where menus would not work on
64 bit builds.

53a6f7b783 eglfs: Fix raster windows
Also sanitize the initial WebAssembly hack. Both eglfs and wasm lack the concept
of true raster windows. A QWindow with RasterSurface is rendered with OpenGL
no matter what. The two platforms took two different approaches to work around
the rest of the machinery:

- wasm disabled the QOpenGLContext warning for non-OpenGL QWindows,

- eglfs forced the QWindow surfaceType to OpenGLSurface whenever it was
  originally set to RasterSurface.

Now, the latter breaks since c4e9eabc30, leaving
all raster window applications failing on eglfs, because flush in the backingstore
is now checking the surface type and disallows OpenGLSurface windows. (just like
how QOpenGLContext disallows RasterSurface windows)

To solve all this correctly, introduce a new platform capability,
OpenGLOnRasterSurface, and remove the special handling in the platform plugins.

fccb519809 Don't rely on QWidget::internalWinId in QWidgetBackingStore
QWidget does not handle QWindow and QPlatformWindow being destroyed
behind its back, and the QWidget state for internalWinId and the
Qt::WA_WState_Created attribute can easily get out of sync with
reality.

To avoid QWidgetBackingStore mistakenly thinking that a widget does
not have a platform window it can operate on we use the QWindow and
QPlatformWindow handles directly, instead of relying on the winId.

This is a stop gap until we can teach QWidget to deal with dynamic
changes to its underlying window handles.

787e498487 QMutexPool: fix memory order of atomic operations
The array of QAtomicPointer<QMutex> can be initialized using relaxed
stores of nullptr, since nullptr is the whole data. But once we store
an actual QMutex pointer in the array, we need to publish the indirect
data thus created. We did this, with testAndSetRelease(); what was
missing was a corresponding acquire fence on load, without which there
is no happens-before relationship between the writes performed by the
QMutex ctor and the reads performed by a subsequent mutex.lock(), say,
on the same data.

Fix by adding acquire fences to all loads. That includes the dtor,
since mutexes may have been created in different threads, and never
been imported into this_thread before the dtor is running.

As a drive-by, return a new'ed QMutex that was successfully installed
directly to the caller, without again going through a load-acquire.

64d9492076 Fix race condition on qt_create_tls() on Windows
If this function is called by multiple threads, more than one could
reach the mutex locking and call TlsAlloc(), but only the last one would
save the data. The others would be leaked and, worse, be used by those
other threads.

[ChangeLog][QtCore][QObject] Fixed a resource leak caused by a race
condition if multiple QObjects were created at the same time, for the
first time in an application, from multiple threads (implies threads not
started with QThread).
