sws: implement MMX/SSE2/SSSE3/SSE4 versions for horizontal scaling.

Speed: from 3.9x to 9.6x speed improvement over C, and some small
(up to 15%) speed improvements over existing MMX code (particularly
for bigger filters).

swscale: split hScale() function pointer into h[cy]Scale().
...
This allows using more specific implementations for chroma/luma, e.g.
we can make assumptions on filterSize being constant, thus avoiding
that test at runtime.

swscale: for >8bit scaling, read in native bit-depth.
...
For 9/10bit, it means we don't have to upscale to 16bit before
actual scaling or pixel format conversion, and thus a performance
gain.

swscale: implement >8bit scaling support.
...
This means that precision is retained when scaling between sample

swscale: change prototypes of scaled YUV output functions.
...
Remove unused variables "flags" and "dstFormat" in yuv2packed1,
merge source rows per plane for yuv2packed[12], and make every
source argument int16_t (some where invalidly set to uint16_t).
This prevents stack pollution and is part of the Great Evil Plan
to simplify swscale.

inline for functions that must be inlined for performance reasons.

swscale: fix types of assembly arguments.

This prevents the following compiler warnings: "warning:

variables are only ever used in inline assembly, their type
is actually irrelevant (so the part where it was wrong did
not invoke any buggy behaviour).
