The overlap filter needs to cover a full macroblock vertical edge when the
FIELDTX value for two neighbouring macroblocks is not equal. By changing
the internal ordering of the blocks from row major to column major, we do
not need to reinterlace a FIELDTX coded macroblock before running the overlap
filter.

When not using libavformat for demuxing, AVCodecContext.has_b_frames
gets set too late causing the recovery frame heuristic in h264_refs to
incorrectly flag an early frame as recovered.
This patch sets has_b_frames earlier to prevent improperly flagging the
frame as recovered.

It is possible for there to be multiple encryption init info structure.
For example, to support multiple key systems or in key rotation. This
changes the AVEncryptionInitInfo struct to be a linked list so there
can be multiple structs without breaking ABI.
