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: fix crash with dithering due incorrect offset calculation.
...
ptrdiff_t can be 4 bytes, which leads to the next element being 4-byte
aligned and thus at a different offset than intended. Forcing 8-byte
alignment forces equal offset of dither16/32 on x86-32 and x86-64.

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.

This means that precision is retained when scaling between sample

9/10/16bit YUV).

Remove unused variables "flags" and "dstFormat" in yuv2packed1,

to simplify swscale.
