    Define coding parameters for GF group of 16 · 8679f417

    Propose the coding structure for GF Group of 16 to use the following
    multi-layer design:
      1st Layer: Frame 0 and Frame 16 (ALTREF)
      2nd Layer: Frame 8 (ALTREF2)
      3rd Layer: Frame 4 and 12 (ALTREF2)
      4th Layer: Frame 2, 6, 10, and 14 (BWDREF)
      5th Layer: Frame 1, 3, 5, 7, 9, 11, 13, and 15
    This CL implements the reference frame update for a GF group of 16
    using a look-up table, which is different from the current
    implementation. The motivation behind is to try out various GF group
    coding structures simply through manipulating the look-up table,
    instead of making changes on swapping the reference indexes and
    associated flags throughout the codebase.
