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. svn path=/branches/ntvdm/; revision=60761
