Check whether interrupts disabled via msr Re-implement DPCs. (badly) Implement critical regions Implement kernel apcs (incorrectly)

interrupts run on their own stack now

add KeInitializeTimerEx removed all dispatcher header wait list hacks

fully implemented dpcs (i think) timers implemented-ish

add IsNull method for checking whether a host point to guest memory is null flesh out scheduler further

…oftware by repeatedly checking a field on the KPCR that we've hijacked

This function was implemented, I somehow lost my implementation and had to decompile a build that had the implementation in it. I pasted the source from Hexrays, as is. I've cleaned that source up here

Added a cvar that enables cpu timing fences, and turn it off by default. Removed crusty unused macros in thread.cc

…veral old TranslateVirtual(context->r[13]) calls to GetKPCR

…pt issue is fixed; this decreases cpu usage by 2x to 3x depending on the game.
