Anton Mitrofanov 142e76f105 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.

Based on a somewhat similar idea in FFmpeg's swscale copy.

Ronald S. Bultje 8a8d0ce208 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.

Ronald S. Bultje ef1ee362b3 swscale: implement >8bit scaling support. 
This means that precision is retained when scaling between sample
formats with >8 bits per component (48bit RGB, 16bit grayscale,
9/10/16bit YUV).

Ronald S. Bultje 13a099799e 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.

Ronald S. Bultje ea28175312 swscale: remove alp/chr/lumSrcOffset. 
They are hacks added to reuse the same scaling function for
different formats and they may cause problems when SIMD

C functions.

Ronald S. Bultje c8f487deae swscale: fix YUV420P 9/10bit support. 
Fix handling of input if not in native endianness, and add support for
9/10-bit output. This allows us to force endianness of YUV420P 9/10bit
in the H264/10bit fate tests, which should fix them on big-endian
systems.
