The generic code in utils.c sets the AVFrame.pkt_dts field from the
packet it was supposedly decoded. This does not have to be true for a
fully asynchronous decoder like mmaldec. It could be overwritten with an
incorrect value. Even if the decoder doesn't determine the DTS (but sets
it to AV_NOPTS_VALUE), it's impossible to determine a correct value in
utils.c.
Decoders can now be marked with FF_CODEC_CAP_SETS_PKT_DTS, in which case
utils.c won't overwrite the field. The decoders are expected to set this
field (even if they only set it to AV_NOPTS_VALUE).

This parameter can be used to inform the allocation code about how much
downsizing might occur, and can be used to optimize how to allocate the
packet

The stats are a superset of the quality factor, also allowing the picture type and encoder "PSNR" stats to be exported
This also replaces the native by fixed little endian order for the affected side data
AV_PKT_DATA_QUALITY_FACTOR is left as a synonym of AV_PKT_DATA_QUALITY_STATS

They are used by dnxhd and mpegvideo_enc exclusively, move them to codec
private options instead.

This field is designed for marking codec properties useful to lavc internals.
Two internal capabilities are added:
- FF_CODEC_CAP_INIT_THREADSAFE: codec can be opened without locks;
- FF_CODEC_CAP_INIT_CLEANUP: codec frees memory if initialization fails.

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().
Also move the declaration to internal.h, and add restrict qualifiers
to the declaration (as in the implementation).

This is the most that can be represented with the current channel layout
system. This limit should be raised/removed when a better system is
implemented.
