    Make encoder buffer allocation dynamic · 3807dd82
    Adrian Grange authored
    Frame buffers are now allocated dynamically on-demand.
    Entries in the reference frame map, cm->ref_frame_map,
    may now be set to -1 (INVALID_IDX) to indicate that
    there is not a valid reference buffer in that "slot".
    All slots in the reference frame map are now initialized
    to the empty state (-1) and each buffer is initialized
    to have a reference count of 0.
