Anton Khirnov a6a2282c25 rv30: fix extradata size check.
It has been checking the number of bits in the offset instead of the
actual offset.

Anton Khirnov 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.

Mason Carter 61ae993957 vc1: Fix intensity compensation performance regression
Introduced by 28243b0d35

Intensity compensation is always used once it was encountered, because
v->next_use_ic is never set back to zero.

Reset v->next_use_ic, when resetting v->next_luty/uv.

Martin Storsjö b3189aff8b png_parser: Fix parsing on big endian
Since pc.state is populated by shifting in from the end of the
32 bit word, the content within pc.state is already in native endian
and should not be read with the AV_R{L,B} functions.

This was already done correctly for state64 above.

This fixes the fate-corepng test on big endian.

Anton Khirnov 37a749012a lavc: rework handling of refcounted_frames=0
Use only proper AVFrame API (no assigning of whole frames, since that
hardcodes sizeof(AVFrame) into lavc).

Make a copy of the side data, so the caller can use av_frame_unref/free
on non-refcounted frames, eliminating the need for
avcodec_get_frame_defaults()/avcodec_free_frame().

Not just on failure. This is the same thing that is done in the audio
path and should prevent leaks in decoders that allocate a frame, but
then end up not writing into it.
