Merge remote-tracking branch 'qatar/master'
* qatar/master: (21 commits) swscale: Add Doxygen for hyscale_fast/hScale. fate: enable lavfi-pixmt tests on big endian systems PPC: swscale: disable altivec functions for unsupported formats fate: merge identical pixdesc_be/le tests swscale: Add Doxygen for yuv2planar*/yuv2packed* functions. build: call texi2pod.pl with full path instead of symlink build: include sub-makefiles using full path instead of symlinks swscale: update big endian reference values after dff5a835. wavpack: skip blocks with no samples cosmetics: remove outdated comment that is no longer true build: replace some addprefix/addsuffix with substitution refs avutil: Remove unused arbitrary precision integer code. configure: Drop check for availability of ten assembler operands. aacenc: Save channel configuration for later use. aacenc: Fix codebook trellising for zeroed bands. swscale: change prototypes of scaled YUV output functions. swscale: re-add support for non-native endianness. swscale: disentangle yuv2rgbX_c_full() into small functions. swscale: split yuv2packed[12X]_c() remainders into small functions. swscale: split yuv2packedX_altivec in smaller functions. ...

+ * pixels to interpolate the output pixel. Since you can use at most
