This commit allows the rate-distortion optimization recursion at encoder to go down to 4x4 block size. It deprecates the use of I4X4_PRED and SPLITMV syntax elements from bit-stream writing/reading. Will remove the unused probability models in the next patch. The partition type search and bit-stream are now capable of supporting the rectangular partition of 8x8 block, i.e., 8x4 and 4x8. Need to revise the rate-distortion parts to get these two partition tested in the rd loop. Change-Id: I0dfe3b90a1507ad6138db10cc58e6e237a06a9d6
