* qatar/master: build: improve rules for test programs build: factor out the .c and .S compile commands as a macro swscale: remove unused xInc/srcW arguments from hScale(). H.264: disable 2tap qpel with CODEC_FLAG2_FAST and >8-bit H.264: make filter_mb_fast support 4:4:4 mpeg4videoenc: Remove disabled variant of mpeg4_encode_block(). configure: allow post-fixed cpu strings for athlon64, k8, and opteron when setting the -march flag. Move some variable declarations below the proper #ifdefs. Conflicts: Makefile ffplay.c libswscale/swscale.c Merged-by: Michael Niedermayer <michaelni@gmx.at>
