d9c072aba2 [NTVDM]
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.

2c8e8ba5d3 [FAST486]
- Remove an unneeded inclusion to the CRT header: limits.h (and use instead NDK definitions for max/min long values).
- Remove unneeded comments...
[NTVDM]
Remove an unneeded add_dependencies(...) command.

f5d3c9254c [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.

sufficiently functional.

01d5a36cf5 [NTVDM]
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.

0e8be812b0 [SOFT386]
Implement the hardware interrupt system.
Modify Soft386Interrupt to assume hardware interrupts, because
software interrupts from outside the emulator may cause race conditions.

0c91026f75 [NTVDM]
Change the instruction in the interrupt handlers to "INC SP" twice
instead of one "ADD SP, 2". It's shorter and supported by soft386 already.

Fix prefix handling in some functions.
[NTVDM]
Enable BOPs for Soft386 (when NEW_EMULATOR is defined).
Fix the calling convention issue (softx86 uses cdecl, soft386 uses stdcall).
