Stephen Hutchinson a5387f983d avisynth: adapt 239d02eff3 to dlsym
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.

Stephen Hutchinson b1681bad33 libavformat/avisynth: enable additional pix_fmts
These pix_fmts have been added to FFmpeg in the 31 months since
commit 92916e8542 added support for
the larger number of pix_fmts that AviSynth+ can use. They were
present in AviSynth+ even then, just not in libavutil.

wm4 86a13bf2ff lavc, lavf: move avformat static mutex from avcodec to avformat
It's completely absurd that libavcodec would care about libavformat
locking, but it was there because the lock manager was in libavcodec.

This is more stright forward. Changes ABI, but we don't require ABI
compatibility currently.

Anton Khirnov 9200514ad8 lavf: replace AVStream.codec with AVStream.codecpar
Currently, AVStream contains an embedded AVCodecContext instance, which
is used by demuxers to export stream parameters to the caller and by
muxers to receive stream parameters from the caller. It is also used
internally as the codec context that is passed to parsers.

In addition, it is also widely used by the callers as the decoding (when
demuxer) or encoding (when muxing) context, though this has been
officially discouraged since Libav 11.

There are multiple important problems with this approach:
    - the fields in AVCodecContext are in general one of
        * stream parameters
        * codec options
        * codec state
      However, it's not clear which ones are which. It is consequently
      unclear which fields are a demuxer allowed to set or a muxer allowed to
      read. This leads to erratic behaviour depending on whether decoding or
      encoding is being performed or not (and whether it uses the AVStream
      embedded codec context).
    - various synchronization issues arising from the fact that the same
      context is used by several different APIs (muxers/demuxers,
      parsers, bitstream filters and encoders/decoders) simultaneously, with
      there being no clear rules for who can modify what and the different
      processes being typically delayed with respect to each other.
    - avformat_find_stream_info() making it necessary to support opening
      and closing a single codec context multiple times, thus
      complicating the semantics of freeing various allocated objects in the
      codec context.

Those problems are resolved by replacing the AVStream embedded codec
context with a newly added AVCodecParameters instance, which stores only
the stream parameters exported by the demuxers or read by the muxers.

Stephen Hutchinson 16ae337bd8 avisynth: Use av_packet_from_data instead of av_new_packet
If the audio changes from 9eac7c4 were merged as they were, this
would cause scripts with both video+audio to fail with a lot of
audio decoding errors (the video would be fine). Scripts with
only one of either video or audio were unaffected. Additionally,
the av_packet changes in general caused seeking to break.

Using av_packet_from_data allows video+audio scripts to work as
expected, without audio decoding errors.  It also fixes seeking.

Directly loads AviSynth through LoadLibrary instead of relying on
Video for Windows, and supports using AvxSynth (via dlopen) to
open scripts on Linux and OS X.

Error messages from AviSynth/AvxSynth are now reported through
av_log and exit, rather than the traditional behavior of generating
an error video that the user would need to watch to diagnose.
