This commit was merged in a couple years ago as a no-op because we
had already switched from GetProcAddress to dlsym some time before
that.  However, not applying the actual cast causes warnings about
FARPROC and when attempting to build FFmpeg in MSVC with AviSynth-GCC
32-bit compatibility, those FARPROC warnings turn into FARPROC errors.

Directed to the AviSynth+ entry on AviSynth Wiki rather than to
the github repository, since the wiki page is both more informative
and has the relevant Git/download links.  The github releases page
is little more than a changelog.

It's been fixed both AviSynth+-side and locally.

These pix_fmts have been added to FFmpeg in the 31 months since
commit 92916e85 added support for
the larger number of pix_fmts that AviSynth+ can use. They were
present in AviSynth+ even then, just not in libavutil.

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.

Could not be used in apply_dependent_coupling because of alignment issues.

Ever since 59ad5046, the demuxer expects its seek arg to be PTS
and adjusts internally to search index by DTS.

Assembly failed when using yasm rather than nasm.

The last argument of av_strlcpy is supposed to contain the size of the
destination buffer, but it was filled with the size of the source
string, effectively negating its very purpose.

Replaced VSHUFPS with VPBLENDD to relieve port 5 bottleneck
AVX2 is 1.4x faster than AVX

Prepare for checkasm test.
