Compiler support for lambda functions and variadic templates is
required since Qt 5.7, so no need to mention in the documentation
what happens if the compiler doesn't support it.

On POSIX compliant platforms, the default precision we apply to
preserving time stamps is seconds. However we can do better and use
utimensat() - if available - to increase the precision to nanoseconds.
The values are provided by statbuf's st_mtim. This is guarded for
compatibility with older systems, similar to commit
494ced1329.

The implementation now uses the relaxed-constexpr
qCountTrailingZeroBits() function from QtAlgorithms, making the
QSizePolicy(Policy, Policy, ControlType) constructor constexpr on
C++14 compilers. The explicit check for DefaultType remains to keep
the constructor C++11-constexpr when called with just (Policy,
Policy).
Extend the constExpr tests a bit.

Even though we revoke its Q_COMPILER_UNIFORM_INIT for certain bugs

enough of braced initialization to make the macro magic in

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.

Improves performance when appending temporaries, esp. since
the aliasing fix in the lvalue overload in 0f730ef made that
overload correct, but a bit slower across reallocs.
The unit tests already also pass rvalues, so the function is

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.

A QDockWidgetItem will be leaked if a QDockWidget is dragged out of a
floating tab window, and then plugged back somewhere.
The problem is that QMainWindowLayout::unplug was not returning the
QDockWidgetItem* from the floating tab's layout. When that's the case,
a new QDockWidgetItem is created in QDockWidgetPrivate::startDrag
and will be put into the layout, leaking the old QDockWidgetItem.

Replace an array of pairs of pointers with an array of pairs of
arrays. Remove the unused end marker. Add a static_assert to
verify that the size of the array matches the constant all loops
use.
Also extract the common part of the mime-type name and append it when
building a QByteArray from it. This is free, as both the new
QStringBuilder expression as well as the old construction from a const
char * incur one memory allocation each.
Replace one indexed loop with ranged-for.
