Unix mmap(2) system calls do allow for mapping beyond the end of the
file, though what happens after you try to dereference the pointers it
gives is unspecified. POSIX[1] says that implementations shouldn't allow
it:
The system shall always zero-fill any partial page at the end of an
object. Further, the system shall never write out any modified portions
of the last page of an object which are beyond its end. References
within the address range starting at pa and continuing for len bytes to
whole pages following the end of an object shall result in delivery of
a SIGBUS signal.
However, Linux allows this in read-write mode and extends the file
(depending on the filesystem).
Windows MapViewOfFile never allows mapping beyond the end.

- Test tst_LargeFile::mapFile fails on Qemu for files over 4Gb.
Fixed by limiting maxSizeBits to 28 (must be n*4 and < 32).
- Bug QTBUG-21175 is also effective on ARM targets. Fixed by
expecting failure also on ARM.

From Qt 5.7 -> tools & applications are lisenced under GPL v3 with some
exceptions, see

(in those files which will be under GPL 3 with exceptions)

msvc2015 reintroduced a couple of functions from the win32 API

Enable usage of those and simplify the file system engine.
Furthermore update the autotests.

Qt copyrights are now in The Qt Company, so we could update the source
code headers accordingly. In the same go we should also fix the links to
point to qt.io.
Outdated header.LGPL removed (use header.LGPL21 instead)
Old header.LGPL3 renamed to header.LGPL3-COMM to match actual licensing
combination. New header.LGPL-COMM taken in the use file which were
using old header.LGPL3 (src/plugins/platforms/android/extract.cpp)
Added new header.LGPL3 containing Commercial + LGPLv3 + GPLv2 license
combination

It's usually a bad idea to surround slots or signals with #ifdef since
moc may not parse it the same way the compiler does.
