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).

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.
