In NEWMV mode, currently, full search is used as the refining search after n-step search. By replacing it with an iterative diamond search of radius 1 largely reduced the computation complexity, but still maintained the same encoding quality since the refining search is done for every macroblock instead of only a small precentage of macroblocks while using full search. Tests on the test set showed a 3.4% encoding speed increase with none psnr & ssim loss. Change-Id: Ife907d7eb9544d15c34f17dc6e4cfd97cb743d41
