In addition to pen events being handled as tablet events, we create
touch events. Same principle is used on other platforms as well. This
allows devices as Surfaces to use the pen with Qt applications.
Furthermore, the first update event does not have to be a press event,
as in a pen has proximity values describing a move without touch, but
also the HoloLens uses touch points as permanent pointer devices. They
all send an exit event once released or out of range. Hence, clean up
the internal touchpoint hash when the touch device is gone, not on
release.

The MSVC STL warns when passing naked pointers as non-bounded
iterators to algorithms such as std::equal and std::copy, in
an attempt to inform users that the range specified by that
iterator has an implicit minimum size that the caller of the
algorithm must ensure is met:
warning C4996: 'std::_Equal1': Function call with parameters that may be unsafe - \
this call relies on the caller to check that the passed values are correct. To \
disable this warning, use -D_SCL_SECURE_NO_WARNINGS. See documentation on how to \
use Visual C++ 'Checked Iterators'
When building Qt, as well as when building user projects with
qmake (cf. 0a76b6bc7f), we
globally disable this warning (with -D_SCL_SECURE_NO_WARNINGS),
but since we started using STL algorithms in public headers (e.g.
in qvector.h), users get this warning in their own projects now,
unless they, too, define said macro. But such a requirement is
against the Qt policy to have headers that are warning-free as
much as possible.
The suggested way of fixing this warning is to wrap the naked
pointer in a stdext::unchecked_array_iterator before passing it
to the algorithm, cf. examples in
https://msdn.microsoft.com/en-us/library/ttcz0bys%28v=vs.120%29.aspx
or, together with the capacity-made-explicit, in a
stdext::checked_array_iterator.
To avoid ifdefs for platforms that don't have these extensions
(which, incidentally, for the unchecked case, includes MSVC 2012),
wrap the calls in macros.
The end game here is to drop -D_SCL_SECURE_NO_WARNINGS, at least
for public headers, even though this commit also adds the wrapper
to implementation and private header files.
An alternative to the wrapper would have been the version of
std::equal that takes four iterators. However, that is a C++14
library feature, while this version of Qt still needs to compile
with a C++98 compiler, and, more importantly, there isn't, and
never will be, a corresponding 4-iterator version of std::copy.
