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().

frame: cosmetics, reindent

frame: copy flags in av_frame_copy_props()

Flags can be considered metadata (at least those that are defined now).

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
path and should prevent leaks in decoders that allocate a frame, but
then end up not writing into it.

lavc: remove a pointless check in decode_audio4()

av_frame_unref() works fine on unallocated frames.

lavc: use buf[0] instead of data[0] as the indicator of an allocated frame

data[0] may be NULL for valid frames with hwaccel pixel formats.

lavc: remove the extended_data workarounds.

All decoders should now handle it properly.

pthread_frame: use the AVFrame API properly.

Remove the extended_data workaround, all decoders should now handle this
