d66e305bd1 er: move relevant fields from Picture to ERPicture
This is done to disentangle ER from mpegvideo. In order to use a
classic Picture, callers can use ff_mpeg_set_erpic() or use a custom function
to set the fields. Please note that buffers need to be allocated before
calling ff_er_frame_end().

024db24912 mpegvideo: allocate edges when encoding.
Allocating edges will be removed from generic code, so the encoder must

ebfe622bb1 mpegvideo: drop support for real (non-emulated) edges
Several decoders disable those anyway and they are not measurably faster
on x86. They might be somewhat faster on other platforms due to missing
emu edge SIMD, but the gain is not large enough (and those decoders
relevant enough) to justify the added complexity.

aec25b1c46 mpegvideo: split the encoding-only parts of frame_start() into a separate function
This introduces some code duplication. However, much of it should go

feded990e3 mpegvideo: set reference/pict_type on generated reference frames
Otherwise the generic code will unref them, which can then result in
last_picture_ptr == current_picture_ptr, which causes deadlocks at least
in rv40.

2d1f4288dd mpegvideo: call av_frame_unref() instead of avcodec_get_frame_defaults().
This is a temporary workaround to allow deprecating
avcodec_get_frame_defaults(). The proper solution will be using a
properly allocated AVFrame in Picture.

19e30a58fc Deprecate obsolete XvMC hardware decoding support
XvMC has long ago been superseded by newer acceleration APIs, such as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.

5f24fe82e5 mpegvideo: Initialize chroma_*_shift and codec_tag even if the size is 0
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.

3eae9b030c mpegvideo: unref buffers in ff_mpeg_unref_picture on frame size changes
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.

4b79668154 mpegvideo: unref old current_picture before allocating a new one
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.

259af1b923 mpegvideo: allocate sufficiently large scratch buffer for interlaced vid
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.

c3ebfcd6e1 mpegvideo: allocate hwaccel privdata after the frame buffer
This ensures the hwaccel privdata does not leak when a frame buffer could
not be allocated (and toggle the assert when the frame is re-used).
Having no frame buffer available is quite common when using the DXVA2
hwaccel in situations where the DXVA2 renderer is being re-allocated, for
example when moving between displays.
