The bahavior of this function is to compute log2 of mv difference,
i.e. min log2(1 + row_diff * row_diff + col_diff * col_diff)
against available neghbor mvs.
Since the log2 is monotonic increasing, we can compute
min row_diff * row_diff + col_diff * col_diff first
then apply log2 in the end
non_greedy_mv encoding time is reduced by 1.5%

As the boosted frames, early in key frame interval,
are used as reference by many subsequent boosted frames,
boosted frames that are closer to the reference key frame
should be allocated with more target bits than the rest.
Similarly, the active best quality should be lower for
boosted frames early in the key interval and vice versa.
Hence, the bits allocation and active best quality are varied
based on their temporal position in the key frame interval.
