Switch SSSE3 row wrappers from variable sized malloc to fixed size array with loop to process a portion of the row at a time. This helps performance in the case where the image has been coalesced into a single large row and the allocator, although only called once, is slow to clear the pages. Also the smaller temporary buffer fits cache, further improving performance.

Remove bayer format support from libyuv. This format is very rare and used on legacy hardware. Its not well optimized and has bugs related to odd widths. Removing the format will allow tests to pass under more circumstances, run faster and allow focus on higher priority quality and performance issues.

prototype of a YUV to RGB function to achieve higher quality and performance at the same time. The chroma is made more accurate by using negative values that allow more range and then subtract the contributions from the luma contributes. The luma is made more accurate using a multiply that duplicates the Y bits out to 16 bits and then does a 2.14 bit fixed point coefficient. The replication is done for free as part of the multiply.

Change rectangle low level functions to use more conventional row functions including 'any' variations. Previously the yuv function SetPlane stored 32 bit values. Now a more conventional memset() style function is used for YUV that stores bytes. On Haswell a rep stosb is used for YUV. Overall benefit of this CL is improved performance for 'any' width, and simpler row assembly instead of full image assembly. Previously ARGBRect used a low level function that supported a rectangle in assembly. Now it uses a row function, and relies on row coalesce to combine into a single low level call.

Remove unaligned functions, since most function support unaligned memory now. This reduces complexity and improves performance for unaligned cases because C code can be avoided, and overhead is less. Downside is old cpus (core2 and earlier) will be slower for aligned memory case. Except mips, which has alignment requirement, but remove unaligned variant.
