[FAST486]

Separate external interrupts from interrupt signals (which are
interrupts whose number is not known until they can be serviced,
just like hardware interrupts on a real CPU).
[NTVDM]
Improve the PIC emulation code (IRQ priorities, etc...).
Instead of checking for interrupts in the main loop, move the
PS/2 input parsing to a different thread.
Improve BIOS keyboard IRQ handling.
