This avoids allocations and error checks etc. as well as duplicate pointer lists in the CodedBitstreamFooContexts. It also avoids casting const away for use as opaque, as the RefStruct API supports const opaques. The fact that some of the units are not refcounted (i.e. they are sometimes part of an encoding context like VAAPIEncodeH264Context) meant that CodedBitstreamUnit still contains two pointers, one to the content and another ownership pointer, replacing the AVBufferRef* pointer.
