GSdx: Polished the recent changes a bit. Single threaded mode should be back to normal, 2-4 threads might be faster or slower. All in all, it has a lot more potential now. Rendering is almost as separated as with d3d, everything needed is packed and copied for the worker threads, synchronization between local memory and the temporary buffers is properly done. This model could also be back-ported to d3d. Or the software rasterizers could be hardware assisted somehow, there are a lot less sync points where those buffers should match with the contents of the local memory.
