Hack around gcc 4.6 breaking asm using call.
...
gcc 4.6 no longer decrements esp to account for local variables.
Thus using call will end up overwriting some local variable.
So add an extra one it can safely clobber.
This is a huge hack because it's basically pure chance it works,
no idea how this is supposed to be done.
Fixes trac ticket #397 .

This allows using more specific implementations for chroma/luma, e.g.
we can make assumptions on filterSize being constant, thus avoiding
that test at runtime.

Remove unused variables "flags" and "dstFormat" in yuv2packed1,
merge source rows per plane for yuv2packed[12], and make every

to simplify swscale.

This prevents the following compiler warnings: "warning:

variables are only ever used in inline assembly, their type
is actually irrelevant (so the part where it was wrong did
