After running it through my main tests it did find several issues with
the last patch. I do want most of this to get into the next merge
window, so I'm going to drop the last patch and see if the rest have no
issues. This is just a clean up and moving code around. It shouldn't be
too risky. The last patch required getting all the functions from being
static to global and with the right configs, so that's a bit too
complex for this late in the game.
