    Disallow 4:1/1:4 partitions for BLOCK_128x128 · eb123933

    The change can be temporarily reverted by setting ALLOW_128X32_BLOCKS
    to 1 (for easy "is this better?" testing: we'll get rid of the option
    once it's clear what we're doing).
    Since this means we have to modify the "num_partition_types"
    calculation in functions like read_partition, we move it into a helper
    function called partition_cdf_length(). Doing this makes the bodies of
    read_partition and write_partition somewhat simpler than they were.
