avcodec/mips: Split uni mc optimizations to new file This patch moves HEVC code of uni mc cases to new file hevc_mc_uni_msa.c. (There are total 5 sub-modules of HEVC mc functions, if we add all these modules in one single file, its size would be huge (~750k) & difficult to maintain, so splitting it in multiple files) This patch also adds new HEVC header file libavcodec/mips/hevc_macros_msa.h Signed-off-by: Shivraj Patil <shivraj.patil@imgtec.com> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
