    Generalize and increase frame coding contexts · 4b65837b

    Previously there were two frame coding contexts tracked, one for normal
    frames and one for alt-ref frames. Generalize this by signalling the
    context to use in the bitstream, rather than tieing it to the alt ref
    refresh bit. Also increase the number of contexts available to 4, which
    may be useful for temporal scalability.
