Niklas Haas 4c19f82cc0 swscale/ops_dispatch: compute minimum needed tail size ...

Not only does this take into account extreme edge cases where the plane
padding can significantly exceed the actual width/stride, but it also
correctly takes into account the filter offsets when scaling; which the
previous code completely ignored.

Simpler, robuster, and more correct. Now valgrind passes for 100% of format
conversions for me, with and without scaling.
