Enable recursive partition information coding from SB64X64 down to MB16X16. The bit-stream syntax is now supporting rectangular block sizes. It starts from SB64X64 and recursively describes the partition type of the current block. If the partition type is PARTITION_NONE, the block is coded as a single unit; if it is PARTITION_HORZ or PARTITION_VERT, the block is segmented into two independently coded rectangular units, with no further partition needed; otherwise, the block is segmented into 4 square blocks. i.e., PARTITION_SPLIT case, each can be potentially further partitioned. Forward adaptive probability modeling is used for the partition information coding, conditioned on the current block size. Change-Id: I499365fb547839d555498e3bcc0387d8a3587d87
