Required for implementing upcoming QStringView's member functions such
as compare(), indexOf(), endsWith(), ...
Most implementations of the function body just add the length to the
begin pointer to obtain an end pointer and then either no longer use
the length, or decrease it in lock-step with increasing the begin
pointer.
The only exception is MIPS DSP's qt_ucstrncmp_mips_dsp_asm(), which
gets the length passed in as an uint, implicitly converted from the
int parameter, proving that calling the function with negative length
was always undefined behavior, and therefore using an unsigned type
does not introduce incompatibilites.
I don't stand a snowball's chance in hell to fix the assembler
routine, but since the code is only included for MIPS32, we don't need
to do anything except be paranoid, add a static_assert that uint is
the same size as size_t, and keep calling the old code.
Dropped Q_COMPILER_LAMBDA in some places. We require lambdas since 5.7.
Also hold lambdas by value, not by reference. This stuff is supposedly
completely inlined, anyway, so there's no reason to make the code more
complicated with magic lifetime extension of temporaries bound to
references.

The extension of ucstrncmp to size_t will introduce the first user
of this loop unrolling construct with size_t indices.
Instead of choosing between int and size_t, make the index type a
new template argument to facilitate a step-by-step transition from
int to size_t users.

The cumbersome complex calls to QMatrix were surely easy to write
thanks to copy-and-paste; but this left the reader to either
laboriously check or guess that all the copies were the same (and
notice that there were two, in fact). DRY.
Since QMatrix wants qreal data, change the float deg angle to a qreal
and work in qreal throughout. Passing the angle to a function instead
of repeating it obviates the need for a local variable in the calling
code, to hold its value.

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.
