Merge remote-tracking branch 'qatar/master'

* qatar/master:
  FATE: add tests for targa
  ARM: fix Thumb-mode simple_idct_arm
  ARM: 4-byte align start of all asm functions
  rgb2rgb: rgb12to15()
  swscale-test: fix stack overread.
  swscale: fix invalid conversions and memory problems.
  cabac: split cabac.h into declarations and function definitions
  cabac: Mark ff_h264_mps_state array as static, it is only used within cabac.c.
  cabac: Remove ff_h264_lps_state array.

Conflicts:
	libswscale/rgb2rgb.h
	libswscale/swscale_unscaled.c
	tests/fate/image.mak
