Let's just call this MpegWarmUp. We might find other uses.

OK, for now. I hope eventually we can find a universal solution to these instead of relying on compat.ini hacks.

I'm obviously not a fan of the idea of having an array of warm up flags for every HLE function. If we have to do this though, MpegAvcWarmUp would be a better name.

I think we need to figure out what the actual variables are that cause the delay, which btw is seen in most pspautotests of Mpeg even with firmware 1.50 set.
