* commit 'd338abb6':
  mpeg4videodec: Call av_log() in check_marker() with AVCodecContext instead of NULL

This commit is a noop.

Since check_marker() is still in get_bits.h in FFmpeg and shared amongst
decoders, a similar but different change will be committed in the next
commit in to serve the same purpose of this one (that is, passing a
logging context to the av_log() in that function).

* commit 'e4b38878':
  Move check_marker() from get_bits to mpeg4videodec

Not merged, check_marker() is used in various other places in FFmpeg.

* commit '763d69bf':
  Add some more deprecation guards

- psnr() deprecation is not merged within ffmpeg.c as we still use it in
  non-deprecated code

- the XVMC chunk is not merged as we still apparently maintain it

- The guarding in lavc/qtrleenc.c could be simplified but merged anyway.
