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().

a1ee164869 lavc/decode_video(): always unref the frame if there is no output in decode_video
Not just on failure. This is the same thing that is done in the audio

d085f80fa1 webp: add a special case for a huffman table with only 1 symbol
The vlc reader cannot handle 0-bit huffman codes. For most
situations WebP uses the "simple" huffman coding for this case,
but that will only handle symbols up to 255. For the LZ77 distance
codes, larger symbol values are needed, so it can happen in rare
cases that a normal huffman table is used that only has a single
symbol.

24abd806ea ljpegenc: deMpegEncContextize
The encoder uses almost none of the mpegvideo infrastructure, only some
fields from MpegEncContext.

The FATE results change because now an all-zero quant matrix is written
into the file. Since it is not used for anything for ljpeg, this should
not be a problem.

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.
