James Almer df3a2ff767 avcodec/cbs: use a reference to the assembled CodedBitstreamFragment buffer when writing packets 
This saves one malloc + memcpy per packet

The CodedBitstreamFragment buffer is padded to follow the requirements
of AVPacket.

Mark Thompson 7157d95926 cbs_h264: Move slice_group_id array out of PPS structure 
It's very large, and is only used in some FMO streams.

Mark Thompson ce5870a3a8 cbs: Refcount all the things! 
This makes it easier for users of the CBS API to get alloc/free right -
all subelements use the buffer API so that it's clear how to free them.
It also allows eliding some redundant copies: the packet -> fragment copy
disappears after this change if the input packet is refcounted, and more
codec-specific cases are now possible (but not included in this patch).
