s/AV1_ADST8/AOM_ADST8/
The code in idct8x8_msa.c and inv_txfm_msa.h fell out of sync with:
80edfa0 Change "VP9" to "AV1"
and
ff00fc0 Change "VPX" to "AOM"
the other instance in av1/encoder/mips/msa/fdct_msa.h was renamed to
AOM_ADST8. these modules could use further harmonization regarding AV1_
vs AOM_

The tables av1_kf_uv_mode_prob[INTRA_MODES][INTRA_MODES - 1] and
av1_kf_partition_probs[PARTITION_CONTEXTS][PARTITION_TYPES - 1] are not
referenced anywhere in vp10 or av1 and can be removed.

This commit makes the codec to store the predicted motion vector
at 8x8 block level and assign them when the reference motion vector
is obtained from collocated blocks in the previous frame.

This commit enables motion estimation process based on the dynamic
motion vector referencing system. It allows the codec to select
the optimal predicted motion vector for motion vector coding.

This commit allows the compound mode to use entropy coding contexted
on the dynamic motion vector referencing system.
Change-Id: Ie6f3219183ac3fce322d340728af26c1c1dfa37f
This allows the codec to use effective motion vector as the candidate
to produce the reference motion vector list.

The old taps were equivalent to [2 2 3 2 3 2 2], while the new taps are
equivalent to [1 2 3 4 3 2 1]. The new coefficients improve metrics
slightly (not clear why).

This commit enables the dynamic reference motion vector coding mode
for the compound inter blocks.
Change-Id: I3d6edea7cf241cbb108709b57aeb54f811029237
This commit generalizes dynamic reference motion vector coding mode
to support multiple candidate modes in the rate-distortion
optimization scheme and to support the selection in the bit-stream
syntax. The maximum number of modes allowed is currently limited to
4. The syntax elements for the dynamic reference motion vector
modes are using binary codes.
