Performance improvements for the Raspberry Pi

[andrew-hoffman]

Well not just the Raspberry Pi. A lot of this would help anywhere. Thanks so much.

I'd like to merge as much of this as possible, and it's probably about time to completely replace the old Swing UI as it's inexcusably slow when resizing images, can't get vsync and just doesn't have much of a future.

Would it be possible to add a toggle for per-line computation using these improvements, as well as the bitwise enhancements? I don't know enough about the Pi to remove the Pi stuff that wouldn't be appropriate in the master branch.

I already manually applied a lot of the changes in this PR but have not
reimplemented the old line at a time PPU because I had to make some
extensive changes to the mappers and the way CPU to PPU sync is done to
move away from that in the first place. The PR is still around to remind me
to work on making the rewritten interface for the Pi to work on PC but I
haven't had time to do much of anything to HalfNES lately as I am trying to
finish up grad school and look for work.

Okay, if I need the extra speed badly enough I'll try learning the innards of the emulator to make it configurable for speed vs. accuracy.
