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: handle gray16 as a "planar" YUV format (Y-only, of course).
...
This allows removing any gray16-specific code, which is essentially
identical to the per-plane code in yuv2plane*().

"dstw" can collide with the word-version of the "dst" argument, causing

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.
