x86, setup: "glove box" BIOS calls -- infrastructure
Impact: new interfaces (not yet used)
For all the platforms out there, there is an infinite number of buggy
BIOSes. This adds infrastructure to treat BIOS interrupts more like
toxic waste and "glove box" them -- we switch out the register set,
perform the BIOS interrupt, and then restore the previous state.
