    Use Daala entropy coder to code trees. · 43acafde
    Nathan E. Egge authored
    When building with --enable-daala_ec, calls to aom_write_tree() and
     aom_read_tree() will convert a aom_tree_index structure with associated
     aom_prob probabilities into a CDF on the fly for use with the
     od_ec_encode_cdf_q15().
    The number of symbols in the CDF is capped at 16, and trees that contain
     more than 16 leaf nodes are handled by splitting the most likely, e.g.,
     highest probability symbols, first and coding multiple symbols if
     necessary.
