This allows simplifying the Makefiles; it is no longer necessary to register

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.

Disadvantage is that it no longer allows modifying brightness through
adjustment of the RGB lookup table. Advantage is that now monowhite/black
no longer need to be identified as a RGB format.
