Change childWidget->windowHandle() to childWidget->internalWinId() in
q_createNativeChildrenAndSetParent() to determine whether should we call
childWidget->winId().
This is because in some circumstances Qt will crash due to accessing
deleted QWidgetWindow object if we use windowHandle(). Think about the
following scenario:
1) create a widget A without parent and add two child widgets B and C to A
2) create a native widget D as the child of B, note that when we set
Qt::WA_NativeWindow attribute to it, its QWidgetWindow will be created
which means its windowHandle() is not null.
3) create a top level widget E as the child of C and show it. This will
make Qt call createWinId() to A and then
q_createNativeChildrenAndSetParent() will be called to create A's native
children recursively and finally make D's QWidgetWindow object become a
child of A's QWidgetWindow object. Please note here that B will not become
a native widget just because at that moment windowHandle() of D is not
null and Qt will not call winId() to its parent B
4) Set A's parent to another widget which has been shown, setParent_sys()
will be called to A and then Qt will call destroy() to A. in destroy() Qt
will try to call destroy() to its children recursively with a condition that
the child has Qt::WA_NativeWindow been set. But D's parent B is not a native
widget right now so B and D is not destroyed. Qt will then deleted the
QWidgetWindow object of A, since E's QWidgetWindow object is a child of
A's QWidgetWindow object, it will also be deleted. Now E hold a deleted
pointer of QWidgetWindow object. This is the source of crash later.

QtWayland uses QtWaylandScanner to generate c++ files which will be
subclassed. This works ok in QtCompositor as it implements the pimple
pattern. However, QtWayland has to expose a library called
QtWaylandClient as a way to create specialized wayland plugins. These
classes don't promise an ABI, and has limited API guarantees, so they
subclass the classes generated by the QtWaylandScanner directly. For
this library to be possible, we have to install the generated files.
Also, it should be possible to use the private API, and that's not
possible without the generated files.

For the linuxfb platform the screen was registered
before its geometry was calculated resulting that
the qpa controller will deal with a screen instance
that has geometry of QRect(0,0,1,1) .
This masks pretty much all the painting and the input.
The fix is to call screen init before registering
the screen instance to the qpa controller.

The QVarLengthArray inside qlocale_blackberry.cpp was being preallocated with
512 bytes, that means internally it could grow up to 512 bytes using the
stack before switching to the heap, but its actual semantic size was still 0.
After qt_safe_read(... buffer.data() ...) was being called, data was written
to the QVarLengthArray buffer, but its semantic size was still 0, since it was
not resized or anything. This triggered an assertion when buffer[bytes] = '\0'
was assigned, since 'bytes' > buffer.size() ( == 0) despite buffer.capacity()
== 512.

Window buffers are currently always created with an alpha channel when
the underlying display supports them. This is the correct thing to to
in order to support translucency. However, the cost is that the
composition manager unconditionally performs blending even when the
use-case in the GUI doesn't make use of it. That is rather expensive,
particularly on hardware which doesn't have extremely efficient
dedicated 2D blitting hardware.
This patch adds inspection of the user's requested window format
and--if no blending is desired--sets an additional Screen window
property which permits Screen to skip blending on the window surface.
