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.

2aa8e33d7d Fix nonsense MPEG-4 hwaccel code. 
Issues with the code:
1) The skip_bits_long breaks packed B-frames since we skip
of the packed frame, even for VDPAU.
2) Calling ff_h263_find_resync_marker_reverse is nonsense for MPEG-4,
and for H.263 the only code using this (vaapi_mpeg4) explicitly reverts
this change!
3) mb_x/mb_y are always 0 when vaapi_mpeg4_decode_slice, so doing
computations with them is just obfuscation
4) due to not updating mb_y the code would always go into the error
resilience case, causing nonsense error messages and maybe further
issues.

While tested to fix the data provided to the decoder in case of
VDPAU so it is the same as for the non-hwaccel code, the VA-API code
was not tested to still work, and adding regression testing even
as a quick hack is much more complicated for it.

f76b633a94 mpeg4dec: Ensure data is not clobbered too early. 
Avoid overwriting the bitstream buffer data before we
have ended processing the frame.
This is necessary to fix hwaccels which might try to use
the buffer during the end_frame call.
I am not sure but it is possible this could even trigger
a use-after-free if the av_fast_malloc allocated a new buffer.
This would require that decode_slice did not wind the bitstream
forward all the way to the end, which does not currently happen in
normal streams.
