dd7058898c xcb: don't do mouse synthesis from touch unless we find a reason
One reason is when we are using XInput 2.2, because touch devices
will then generate touch events only.  For the other X11 scenarios,
X11 does its own mouse emulation.

QPlatformIntegration::styleHint() wasn't overridden yet.  The remaining
hints are TODO for now.

87d08acf40 iOS: Set context and bind FBO before allocating render-buffer storage
defaultFramebufferObject() may be called from anywhere, at any point,
not just makeCurrent(). One example is the glyph-cache, which uses it
to re-bind the default FBO after generating the texture cache.

If the default FBO had already been created, but the render-buffer was
out of sync with the window size, we would end up in the resize code
without the correct context current, and without the render-buffer's
owning FBO bound. This caused "Failed to make complete framebuffer
object 8cd7" warnings at runtime.

We now make the context current and bind the FBO, even though it might
already be bound and the context current from makeCurrent(), or when
initially creating the FBO. For the future we should move the whole
resize logic out of defaultFramebufferObject() and call it from
makeCurrent(), or possibly [EAGLView layoutSubviews]. That's a
higher impact change though, which we reserve for the 'dev' branch.

8dfeb1c374 Don't use GL_REPEAT for image-brush drawing on OpenGL ES2
OpenGL ES2 doesn't support NPOT textures in combination with GL_REPEAT,
so for OpenGL ES2 we use a custom program that emulates repeat by taking
the fractional part of the texture coordinates.

This is not enough though, as merely setting GL_TEXTURE_WRAP_x to GL_REPEAT
with a NPOT texture is an error in some implementations, so we have to
guard the call to updateTextureFilter() in updateBrushTexture() with
a check for OpenGL ES2 and use GL_CLAMP_TO_EDGE instead.

This fixes missing/black backgrounds in the diagramscene example on iOS.

9504516847 Remove the crash pending warning
Even though the intentions of this warning were good, the warning
was a bit harsh. In addition, in certain circumstances
(like the autotest demonstrates) we could end up calling object()
on an interface where the object was in the destructor. This
could happen because: *after* we got the destroyed() signal, the
widget would still notify the accessibility framework of a FocusOut
event.
Since the code even called object() from isValid(), we could not even
(as a defensive measure to circumvent this issue) check the isValid()
of an interface without getting this warning (duh).
So - for isValid(), the warning is not needed at
all, since the caller will of course check the result of isValid() and
act accordingly.

As for the result of object(), it should always be a pointer, but it
might point to a partially destroyed object. To detect this, you simply
check isValid() first:

if (iface->isValid())
    doStuff(iface->object());

522c7ba1ac Enable bundling Qt in Android package in build system
For bundling Qt, we need two things:

1. We need to build a regular .jar file out of the Java files,
so that they can be built into the app package. Dexing the
classes first (i.e. compiling the JVM bytecode to Dalvik
bytecode) is required for loading the .jar file at run-time,
but cannot be used for building it into the app, so we need
two different paths.

2. We need to specify which extra files have to be bundled for
each module (this is primarily for plugins and imports). This
is because there is no static dependency on these files, so
it cannot be detected during deployment.

94bed3ad14 Make it possible to bundle Qt libraries in Android apk
Add the enablers so that Qt Creator (or another
deployment tool) can add a specification in the app's
meta data of which libraries are bundled and the
Java code required to extract plugins and imports into
the required directory structure inside the app's
data directory.

This is intended to be an alternative to using Ministro
for deployment, and the mechanism of extracting
libraries on first startup is a work-around for the
requirement in Qt of having this directory structure.
For Qt 5.2, the approach should be changed to load
plugins directly from the app's lib directory and
the other files in imports will be bundled as qrcs
in the native plugins.

130b579a16 iOS: Don't use -1 as magic value for UIDeviceOrientationFaceUp/Down
The check in [QIOSOrientationListener orientationChanged] ensured we
never reported the two unsupported orientations through QPA, but we
were reporting back the orientation through QIOSScreen::orientation()
as well, and that didn't have a guard for -1. This resulted in crashes
in client code that assumed the range of QScreen::orientation() was
defined by the enum, such as the paintedwindow example.

The listener now ignores the two unsupported orientations, which leaves
us at the previous orientation. For the conversion function, we still
have to support all UIDeviceOrientations, so we fall back to portrait
for the two unsupported orientations. In the future we should consider
caching the previous value explicitly, or fall back to the interface
orientation.

02e406ac50 iOS: Don't pretend like our OpenGL context is single-buffered
Internally iOS double-buffers its rendering using copy instead of flipping,
so we reported that our context was single-buffered so that clients could

Qt itself) then assumed that calling swapBufferes() was not needed.

We now properly report that we're double-buffered, and we'll have to find
another way to report the way double-buffering works if that's still an
optimization we'd like to provide to clients.

d59e9af592 Make sure window is updated on resize event
After 475d1ed4f6a21686828fbd018542b469a8b2dbcd in qtdeclarative,
orientation changes on Android were broken, because the resize
event no longer implicitly causes an expose event. So we need
to post both when doing the resize.

The mips/uclibc features.h of the toolchain used by a former key
account of PSO is defining both __USE_XOPEN2K and __USE_BSD this
will lead to POSIX_MADV_* and MADV_* being defined while only the
symbols for madvise are present. Change the order to make it link.

529b648ece Fix possible race in QMutex
As described in the QTBUG-30872, there may be a race condition involving
3 threads fighting for a mutex.  I am surprised it was not caught
before despite all the Q_ASSERT and the stress test in tst_qmutex.

We do not need to call store(0) because the unlocking thread will
eventually remove the BigNumber flag. And perhaps it even did it
already, and another thread has incremented waiters (hence the Q_ASSERT
is wrong)

Here is a paste of part of the description from the bug report:

---
many threads, one of them is ready to release mutex, while at least two other trying to acquire it
d->waiters is 0
Thread 1 release mutex in unlockInternal:

   if (d->waiters.fetchAndAddRelease(-QMutexPrivate::BigNumber) == 0)

d->waiters is now -QMutexPrivate::BigNumber
Thread 2 try to acquire mutex in lockInternal:

   old_waiters = d->waiters.load();
   if (old_waiters == -QMutexPrivate::BigNumber) {
   if (d_ptr.testAndSetAcquire(d, dummyLocked())) {

It acquire 'about to release mutex' by changing d to dummyLocked
Thread 1 continue release procedure:

   d->derefWaiters(0);

d->waiters is now back to 0
Thread 3 try to acquire mutex in lockInternal:

    while (!d->waiters.testAndSetRelaxed(old_waiters, old_waiters + 1));

d->waiters is now 1
Thread 2 continue its dummy lock:

    d->waiters.store(0);

d->waiters is force to 0

Thread 3 continue wait procedure
but it realize that mutex was already unlocked so decrease back waiters

   if (d != d_ptr.loadAcquire()) {
   if (old_waiters != QMutexPrivate::BigNumber) {
   d->waiters.deref();

d->waiters became negative value of -1
Neither thread need internal data so it is released back to pool
The waiters counter in released internal structure is still -1

We can simply clip the update rect against the widget's rect and return
if it's empty. Otherwise we risk ending up with update rects that are
larger than INT_MAX due to multiple update rects being merged.

c29cbfa858 Get rid of this hack where QAccessible inherits from QObject.
This was added just so that moc could pick up the enums and so that
we could use the enums in Q_PROPERTY declarations, which was needed for
accessibility in QML. It turns out that Q_GADGET is enough for us.

This is a strictly a binary compatible change.
However, QAccessible was marked internal in 5.0, so we are free to
change it. In addition, this class is static and cannot be instantiated.
