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.

This allows using more specific implementations for chroma/luma, e.g.

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: 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.
