New Motion Reference Search Alternative strategy for finding a list of candidate motion vectors to use as reference values in mv coding and as nearest and near. Sort by sad in vp8_find_best_ref_mvs() rather than just pick the best. Allow 0,0 as a best ref option but not a nearest or near unless there are no alternatives. Encode/Decode verified on at least some clips. Some commented out experimental and stats code still in place. Gain over existing code averages about 1% on derf (alll metrics) with improvement on all clips. Other test results pending. The entropy coding of the mode (nearest/near etc) still depends upon and requires the old "findnear" code so this needs looking at and may provide room for further gains.

Use standard integer types for pixel values and coefficients. For coefficients, use int16_t (instead of short); for pixel values in 16-bit intermediates, use uint16_t (instead of unsigned short); for all others, use uint8_t (instead of unsigned char).
