b18f8cbf3d Revert two swscale commits. 
Revert "swscale: update context offsets after removal of AlpMmxFilter."
(commit a95e3fa90b)
and
Revert "swscale: Remove some write-only variables related to alpha handling."
(commit 9d03cb9fc5).

They broke alpha handling - it's the evil inline asm that still uses that
variable, so it's not truely write-only.

It is obscure, most likely unused and not bit-exact compared to
libavcodec due to a different IDCT transform algorithm.

3f04ab4fcd 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.

62ee0e6a97 Revert "swscale: use 15-bit intermediates for 9/10-bit scaling."

causes valgrind errors which I'll want to investigate before
resubmitting this.

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.

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.

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).

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.

ea28175312 swscale: remove alp/chr/lumSrcOffset. 
They are hacks added to reuse the same scaling function for
