Updated the 5170 BIOS map, updated 8042 info, fixed some 8042 controller commands, made HLT work, and fixed the debugger's history buffer when executing a mix of real-mode and protected-mode instructions

* TODO: This was originally used by opHLT(), but this seems rather pointless in hindsight, because
* this call will only end the current stepCPU() iteration; we'll immediately go back into stepCPU(),
* except that X86.INTFLAG.HALT will be set, so we won't execute any more instructions, not even opHLT(),
* until a hardware interrupt is acknowledged. However, it would still be nice if we could reduce CPU
* overhead while in a halted state.
