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

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.
