The most interesting parts are initialization in ff_MPV_common_init() and
uninitialization in ff_MPV_common_end().
ff_mpeg_unref_picture and ff_thread_release_buffer have additional NULL
checks for Picture.f, because these functions can be called on
uninitialized or partially initialized Pictures.
NULL pointer checks are added to ff_thread_release_buffer() stub function.

The old implementation is unusable due to changes in the Xvid API.

Sandy Bridge Win64:
180 cycles in ff_synth_filter_inner_sse2
150 cycles in ff_synth_filter_inner_avx
Also switch some instructions to a three operand format to avoid
assembly errors with Yasm 1.1.0 or older.

The assumption of (MPEG) Picture and H264Picture layout matching might
not hold true in the future.

This allows proper muxing and seeking in things like MPEG-TS, by
placing headers by random access points.

This was only used in hevc muxing code so far.
This makes the return values match what get_se_golomb returns for
the same bitstream reader instances.
The logic for producing a signed golomb code out of an unsigned one
was based on the corresponding code in get_se_golomb, which operated
directly on the bitstream reader buffer - not on the equivalent
return value from get_ue_golomb.
