As part of the update, it is now possible to test 32-bit GCC builds
of AviSynth+ with FFmpeg by using the AVS_WIN32_GCC32 define. Due to
different calling conventions between MSVC and GCC regarding 32-bit
Windows, this is unfortunately necessary.
This removes the XP compatibility code, and switches entirely to SRW
locks, which are available starting at Windows Vista.
This removes CRITICAL_SECTION use, which allows us to add
PTHREAD_MUTEX_INITIALIZER, which will be useful later.
Windows XP is hereby not a supported build target anymore.

External headers are no longer welcome in the ffmpeg codebase because they
increase the maintenance burden. However, in the NVidia case the vanilla
headers need some modifications to be usable in ffmpeg therefore we still
provide them, but in a separate repository.
The external headers can be found at
https://git.videolan.org/?p=ffmpeg/nv-codec-headers.git
Fate-source is updated because of the deleted files, and dynlink_loader.h
license headers were updated with the standard FFmpeg headers.

This avoids having to use either "dumpbin -headers" to find out
the current architecture, or pass $ARCH from configure to deduce it.
When configuring with --disable-asm, ARCH is equal to "c", which doesn't
give any indication of what symbol prefix is to be used.

Since this machine type is 5 chars while the existing ones only
were 3 (which the regexp assumed), the regexp has to be extended
a little.

This is invoked by setting the NM and AR variables to the names of
those specific tools. The ARCH variable also needs to be provided,
to choose the symbol prefix (nm doesn't provide any option that
dumps the architecture easily).

Windows nvcc + cl.exe produce a .ctx file with CR+LF newlines which
need to be stripped to work with gcc.

This only enables dlls that are packaged with the application to be
loaded. Due to the limitations of WinRT/UWP it is not allowed to load
external/system dlls so this cannot be used as a complete replacement
for normal win32 dll loading.

Made appropriate changes to be able to successfully
build C++ files using a Visual C++ build on Windows.
Based on an earlier patch by Kyle Schwarz.
Comments:
-- compat/w32pthreads.h: Made appropriate changes to w32pthreads.h to
get it to build when it is being included in a C++ file and built
with Visual C++. This is mostly a copy of Kyle Schwarz's patch as
described above.
-- configure:
a) Now calling set_ccvars CXX to cause the various CXX_ variables to
be setup properly. For example, with MSVC (Microsoft Visual C++),
this causes CXX_O to be set to -Fo$@ instead of using the default
value. The default value does not work with Visual C++. This
change will also have the impact of correcting CXX_O (and possibly
CXX_C) for other compilers, although this is really only relevant
for the Intel compiler, in addition to MSVC.
b) Now using cl for the C++ compiler for the MSVC toolchain. This is
currently only relevant for building the
Blackmagic/Decklink-related files under avdevice.

The Solaris and Windows emulations of atomic_compare_exchange_strong()
need typecasts to avoid compiler warnings, because the functions they
call expect a void* pointer but an intptr_t integer is passed.
Note that the emulations of atomic_compare_exchange_strong() (except
the gcc version) only work for atomic_intptr_t because of the type of
the second argument (|expected|). See
http://en.cppreference.com/w/c/atomic:
_Bool atomic_compare_exchange_strong( volatile A* obj,
C* expected, C desired );
The types of the first argument and second argument are different
(|A| and |C|, respectively). |C| is the non-atomic type corresponding
to |A|. In the emulations of atomic_compare_exchange_strong(), |C| is
intptr_t. This implies |A| can only be sig_intptr_t.

Supporting the system was a nice joke for the 9 release, but it has
run its course. Nowadays Plan 9 receives no testing and has no
practical usefulness.

The nvidia 375.xx driver introduces support for P016 output surfaces,
for 10bit and 12bit HEVC content (it's also the first driver to support
hardware decoding of 12bit content).
The cuvid api, as far as I can tell, only declares one output format
that they appear to refer to as P016 in the driver strings. Of course,
10bit content in P016 is identical to P010, and it is useful for
compatibility purposes to declare the format to be P010 to work with
other components that only know how to consume P010 (and to avoid
triggering swscale conversions that are lossy when they shouldn't be).
For simplicity, this change does not maintain the previous ability
to output dithered NV12 for 10/12 bit input video - the user will need
to update their driver to decode such videos.
