1) XFB in DC proposal. This impact video plugin interface. WARNING: XFB_Draw is not CPU->VI dependent anymore. It's up to GP now. Except for some 2D homebrews which never use GPfifo&CP but direcly XFB. Well, in other words: emulated VSync is uncorrelated with CPU timings now. Tell me if it's too much hacky.

2) DC/GPfifo work: GP quicker to react. PeekMessages at a more steady rate.
3) Fix XFB address to avoid crash like with Animal Crossing gc. TODO: VI regs need proper typedef and logic.
4) Few misc. changes on the fly.
