API changes, most recent first:
-2015-xx-xx - xxxxxxx - lavc 57.7.0 - avcodec.h
- Deprecate av_free_packet(). Use av_packet_unref() as replacement,
- it resets the packet in a more consistent way.

+ xxxxxx - Deprecate av_dup_packet(), it is a no-op for most cases.
+ Use av_packet_ref() to make a non-refcounted AVPacket refcounted.
