Changes to the asm are not merged, they are left for volunteers or
in their absence for later.
The changes this merge introduces are reordering of the function

XvMC has long ago been superseded by newer acceleration APIs, such as
VDPAU, and few downstreams still support it. Furthermore XvMC is not
implemented within the hwaccel framework, but requires its own specific
code in the MPEG-1/2 decoder, which is a maintenance burden.

lavc: deprecate FF_DEBUG_MV and remove all traces of its use
Merged-by: Michael Niedermayer <michaelni@gmx.at>
This allows supporting files for which the image stride is smaller than
the max. block size + number of subpel mc taps, e.g. a 64x64 VP9 file
or a 16x16 VP8 file with -fflags +emu_edge.

mpegvideo: Initialize chroma_*_shift and codec_tag even if the size is 0
Conflicts:

The chroma_*_shift and codec_tag code was not under a size!=0 check in ffmpeg

This fixes breakage in a few fate tests on certain setups
(that for some reason didn't break on OS X) after the previous
commit (8812a8057). Currently, some video streams are initialized
in ff_MPV_common_init with width/height set at 0 and only changed
to a proper video size with ff_MPV_common_frame_size_change later.
The breakage was diagnosed by Anton Khirnov.

ff_mpeg_unref_picture clears the flag indicating that the frame needs to
be reallocated after a frame size change. Since we have now reference
counted buffers we can unref the buffers immediately.
Allows decoding with only three frame buffers with frame reference
counting. Fixes VAAPI based decoding in vlc which uses only three
frame buffers for the mpegvideo-based codecs.
MPV_decode_mb_internal needs 3 * 16 * linesize bytes of scratch buffer
For interlaced content, linesize is multiplied by two after the allocation
of the scratch buffer, and the dest_cr pointer ends past the buffer.
This patch makes ff_mpv_frame_size_alloc allocate a total of
(aligned line_size) * 2 * 16 * 3 bytes, which suffices even for the
interlaced case.
