Merge remote-tracking branch 'qatar/master'
* qatar/master: fate: Add tests for more AAC features. aacps: Add missing newline in error message. fate: Add tests for vc1/wmapro in ism. aacdec: Add a fate test for 5.1 channel SBR. aacdec: Turn off PS for multichannel files that use PCE based configs. cabac: remove put_cabac_u/ueg from cabac-test. swscale: RGB4444 and BGR444 input FATE: add test for xWMA demuxer. FATE: add test for SMJPEG demuxer and associated IMA ADPCM audio decoder. mpegaudiodec: optimized iMDCT transform mpegaudiodec: change imdct window arrangment for better pointer alignment mpegaudiodec: move imdct and windowing function to mpegaudiodsp mpegaudiodec: interleave iMDCT buffer to simplify future SIMD implementations swscale: convert yuy2/uyvy/nv12/nv21ToY/UV from inline asm to yasm. FATE: test to exercise WTV demuxer. mjpegdec: K&R formatting cosmetics swscale: K&R formatting cosmetics for code examples swscale: K&R reformatting cosmetics for header files FATE test: cvid-grayscale; ensures that the grayscale Cinepak variant is exercised.
