f6774f905f mpegvideo: operate with pointers to AVFrames instead of whole structs
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.

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.

66499f34b5 mpegvideo: do not set current_picture_ptr in decoders
This code was originally added in
5f1948111a to h263 to set decoded frame
pts to some random numbers (removed in
a1c5cc429d) and then cargo culted to other
decoders.

The code is left in h263dec for now, since some part of the decoder
(apparently OBMC) relies on the specific previous frame to be reused.

c2f7417eeb vc1: move MpegEncContext.resync_marker into VC1Context.
The field still remains in MpegEncContext because it is used by the
mpeg4 decoder.

ec7d002e55 vc1, mss2: Check for any negative return value from ff_vc1_parse_frame_header
This is required if we return other error codes than explicitly
-1, which so far has been the only other possible return value
besides 0.

93af2734ee lavc: put FF_IDCT_{VP3,H264,CAVS,BINK,EA,WMV2} under FF_API_IDCT.
This allows us to get rid of them on the next major bump. All of the
above are functionally irrelevant, and most of them are unused, except
the vp3 one, which is used wrongly in the bfin arch optimizations.

802713c4e7 mss2: prevent potential uninitialized reads
The alternative to zeroing on init is setting the corrupted flag in
all cases where pal_pic is not fully written, at the cost of added
complexity.

ede3d6400d MSS1 and MSS2: set final pixel format after common stuff has been initialised
This way it won't interfere with WMV9 initialisation inside MSS2 decoder and
avplay will play it fine.
