Keeping the fake parent window around in a created state means we're
wasting system resources such as native platform views/windows, and
makes it harder to debug the lifetime of these resources.
The fake window will be re-created if re-parented into at a later
point.

QWindowContainer assumed that a widget could never change from
native to non-native. This is not a fact when the window container
is reparented to toplevel and back. In this case, usesNativeWidgets
would be stuck at true, and parentWasChanged() would go down the
native widget path, triggering an assert.
The solution is to always recalculate the usesNativeWidgets bool.

Embeddeding a QWindow via QWidget::createWindowContainer() fails to
deliver the SurfaceAboutToBeDestroyed event. This breaks any OpenGL
or Vulkan based QWindow that releases resources upon this event, and
is particularly critical with Vulkan where the only way to do properly
ordered swapchain - surface cleanup is via this event.
In the non-embedded case close() eventually ends up in an explicit
destroy() in QWindow. In the embedded case destroy() only gets called
from ~QWindow. This then silently breaks since the subclass' reimplemented
event() virtual is not getting called anymore.
To remedy the problem, simply add an explicit destroy() to
QWindowContainer.

If, after checking a condition, we issue a qWarning(),
by definition that check is unlikely to be true.
Tell the compiler so it can move the error handling
code out of the normal code path to increase the
effective icache size.
This change contains the changes to the accessible/,
effects/, kernel/, styles/ and itemviews/ subdirs.
Moved conditional code around where possible so that
we could always use Q_UNLIKELY, instead of having to
revert to Q_LIKELY here and there.
In QWidgetPrivate::setWindowModified_helper(), as a
drive-by, I swapped the evaluation order of an
&&-expression (newly wrapped in Q_UNLIKELY) to be
more readable and more efficient (cheaper check
first) at the same time.
In qDraw* (qdrawutil.cpp), simplified boolean
expressions (sometimes by skipping re-checking
conditions already checked in a previous guard clause).

Application that do not require OpenGL need a way to opt-out of
GLX/EGL calls completely. The initialization can be expensive and what
is more, some systems may not have functional GLX at all (some VMs are
known to crash when trying to get FBConfigs for the window).
QApplication already has AA_ForceRasterWidgets, which causes the use
of plain RasterSurface everywhere instead of RasterGLSurface. Combined
with a trivial check in the xcb backend to skip all the Xlib+GLX/EGL
path, the attribute will allow apps to ensure that no GLX/EGL calls
are ever made.
This however implies a change in QWindowContainer: the embedded window
must use the same initialization path as the parent otherwise we will
end up with a BadMatch. QWindowContainer can do this transparently to
the applications, unless the QWindow is already created.

Sometimes Qt wants to hide a widget without calling setVisible(false).
This is usually done by setting the widgets geometry outside the
parents clip rect (and usually by setting its y coordinate to a
sufficiently negative y coordinate). QSplitter uses this when it needs
to collapse its children.
Previously the QWindow was just moved straight above the QWidget it was
hosted in.
