- Move some PS/2 initialization from bios.c to ps2.c
- NULLify interrupt entries which are in fact pointers to data tables.
- Add a framework for adding I/O port handlers.

The PS/2 should latch the last value that was read in the case of multiple reads.
Modify the BIOS keyboard IRQ handler to support hooks.
svn path=/branches/ntvdm/; revision=60773
Implement all the missing INT 16h functions but 03h. Also, for simplification purposes (should be fixed later on) act exactly the same for INT 00h and 10h, and for INT 01h and 11h.
Finally, one has to implement setting the BIOS KeybdShiftFlags flag.
svn path=/branches/ntvdm/; revision=60770
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
Remove the code that performs waiting in 32-bit mode since that blocks the emulator
and prevents interrupts from working.
Implement a 16-bit waiting system in the interrupt handlers.
Fix the PS/2 interrupt code.
