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.

swscale: make access to filter data conditional on filter type.
...
Prevents crashes on 1-tap filter (unscaled). Also rename "bguf" argument
to "vbuf", seems that was a typo.

swscale: make monowhite/black RGB-independent.
...
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.

swscale: fix crashes in yuv2yuvX on x86-32.
...
They were introduced in an earlier commit that introduced use of named
arguments. One cause was a typo, a second cause appears to be a bug in
x264asm that I work around by not using named arguments.

swscale: enforce a minimum filtersize.
...
At very small dimensions, this calculation could lead to zero-sized
filters, which leads to uninitialized output, zero-sized allocations,
loop overflows in SIMD that uses do{..}while(i++<filtersize); instead
of for(i=0;i<filtersize;i++){..} and several other similar failures.
Therefore, require a minimum filtersize of 1.
