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.

678e455f1d dxva2: Directly use AVFrames
The assumption of (MPEG) Picture and H264Picture layout matching might
not hold true in the future.

b66382101c dxva2: Increase maximum number of slices for mpeg2
Some content requires an higher number of slices in order to
render properly.

Rise the number to 1024 and warn if ever it exceeds.

ad0c9f2d5d lavc: move AVFrame.hwaccel_picture_private to Picture.
This field is private and should not be present in a public struct. It
is only used in DXVA with mpegvideo-based decoders currently.

c57a593670 hwaccel: consistent name prefixes for start_frame/end_frame/decode_slice
Some hwaccels use name prefixes, some do not, others only use them for
some codecs.  Add prefixes everywhere for consistency.

2c54155407 h264: deMpegEncContextize
Most of the changes are just trivial are just trivial replacements of
fields from MpegEncContext with equivalent fields in H264Context.
Everything in h264* other than h264.c are those trivial changes.

The nontrivial parts are:
1) extracting a simplified version of the frame management code from
   mpegvideo.c. We don't need last/next_picture anymore, since h264 uses
   its own more complex system already and those were set only to appease
   the mpegvideo parts.
2) some tables that need to be allocated/freed in appropriate places.
3) hwaccels -- mostly trivial replacements.
   for dxva, the draw_horiz_band() call is moved from
   ff_dxva2_common_end_frame() to per-codec end_frame() callbacks,
   because it's now different for h264 and MpegEncContext-based
   decoders.
4) svq3 -- it does not use h264 complex reference system, so I just
   added some very simplistic frame management instead and dropped the
   use of ff_h264_frame_start(). Because of this I also had to move some
   initialization code to svq3.

164aab02a0 MPEG-2 DXVA2 implementation
It allows VLD MPEG-2 decoding using DXVA2 (GPU assisted decoding API under
VISTA and Windows 7).
 It is implemented by using AVHWAccel API.
