It's a Qt 3 compatibility vehicle, and as such inherits the now-alien
property to distinguish empty and null strings. Particularly worrisome
is the following asymmetry:
QString("") == QString::null // false
QString("") == QString(QString::null) // true
Instead of fixing this behavior, recognize that people might use it as
a weird way to call isNull(), albeit one that once was idiomatic, and
simply deprecate everything that deals with QString::null.
[ChangeLog][QtCore][QString] QString::null is now deprecated. When
used to construct a QString, use QString() instead. When used to
compare to a QString, replace with QString::isNull().

For the windows file system engine, we add an extra macro to use
library loading if configured to do so, but avoid it on WinRT, as
none of the symbols would be found.
We also QT_REQUIRE_CONFIG(library) in the library headers and
exclude the sources from the build if library loading is disabled.
This, in turn, makes it necessary to clean up some header inclusions.

This patch fixes 2 issues related to wide menus:
1) Menu took on full screen height when menu width was larger than
screen width;
2) On a multi-display system wide menu might appear on wrong monitor
(not the one where show event was triggered).
The idea is we limit parent menu and all its submenus within the screen
where it was opened.
Note that this patch fixes only geometry-related issues and there are
also some style flaws which need to be addressed (for example, currently
the text does not elide if it doesn’t fit to the menu’s width).

If a floating QWidget has a parent on a different screen, its DPI was
still inherited from the parent instead of taken from the screen.
The only reason we did was in case there is a customDpi set.
(customDpi is a private thing that is only used in designer to change
the appearance of the previewed widget)
So instead of recursing into QWidget::metric for each ancestor, just
use a for loop to find if one parent has a customDpi. If no customDpi
is found, then return the DPI of the right screen.

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.

We always send mouse move events through the application event filters
even if the widget has no mouse tracking enabled. This code portion is
an almost verbatim copy of QCoreApplicationPrivate::sendThroughApplicationEventFilters().
The only difference is that previously the filter and the widget had
to be in the same thread. Now, we compare the filter's thread to the
application's. This is without consequence since widgets must live in
the application thread.
