The definitions of size_t and ptrdiff_t ([support.types.layout] p2 and
p3 respectively) do not specify that they need to be as big as a
pointer. They just need to be big enough to hold the size of the largest
object and the biggest array subscript, respectively, the platform
supports (e.g., 16-bit DOS would have them as 16-bit in all memory
models, except huge).
But we depend on them actually being the size of a pointer in many
places, such as in QArrayData::offset, that stores the linear distance
from the end of the structure to the beginning of the data, wherever it
is in memory.
It's also a good idea to verify that qptrdiff and qssize_t are the same
type.

This variable was introducing during Qt 5.0 Q{Gui}Application
refactoring days (2011 or even before) and since then has been
used interchangeably with QGuiApplicationPrivate::mouse_buttons.
This patch removes the duplicate member variable as it is
redundant and could be a source of potential errors.
Initially I was thinking that ::buttons might be used for
the purpose of QTestLib, but it is not. QTestLib delivers
mouse events directly via qApp->notify() (mouse button state
is update via QGuiApplicationPrivate::mouse_buttons from notify()),
or via window system interface QWindowSystemInterface::handleMouseEvent
(which goes through QGuiApplication::processMouseEvent).
Looking at QGuiApplication, it is clear that ::buttons
and ::mouse_buttons always have the same value, as there
is only one assignment to these members in QGuiApplication:
mouse_buttons = buttons = e->buttons;
And there are no other places that would assign to
QGuiApplicationPrivate::buttons.

Align ourselves to the Standard Library and call std::terminate if an

On platforms using pthreads, thread cancellation needs to be taken in
special consideration, since it looks like it was supported before.
On Glibc, and when using C++, pthread_cancel and pthread_exit are
implemented by throwing a special kind of exception that can be caught,
but must always be rethrown. That exception is then used to activate the
cancellation clean-up handlers. (This is non-Standard C++ behavior.)
So: mimic what libstdc++'s std::thread does to support Glibc's pthread
cancellation.
At this time, it looks like libc++ has no support for this, and when
used in combination with Glibc a thread cancellation results in a crash
(also because it does not seem to terminate() when exceptions leave the
thread).
