Add threading capabilities to overlay filter

I've been running some (entirely unscientific) benchmarks on the overlay filter.

Compositing a frame at 1080p (YUV 422 planar) over another frame takes in the region of around 20ms on my system. Admittedly, my system isn't the latest and greatest.

Having inspected the latest source code, it feels as if the overlay filter (vf_overlay.c) could benefit from threading. The trick would be to somehow keep both the current inlining while incorporating the addition of threading. Without inlining my tests indicate that performance degrades significantly.
