Merge remote-tracking branch 'qatar/master'

* 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
