    This commit makes the buffer allocation of zcoeff_blk array in
    pick_mode_context block size aware. It calculates the number of
    4x4 blocks in the partition and assigns the memory space accordingly.
    This process (and the uninitialization) is done once for each encoding
    pass. It allows memory copy of smaller buffer when possible.
