Aleksandar Andrejevic 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.

Use DOS_CMDLINE_LENGTH instead of MAX_PATH.
Fix bug in DosInitializePsp which allowed writing past the end of the Program Segment Prefix (PSP).

- Use up to 256 parameters for programs (as suggested by the parsing while loop), but don't hardcode this values in many other places.
- The passed command line to ntvdm should be as long as MAX_PATH.

- Enable TESTING by default until the correct way to load ntvdm is found.
- Calculate the character height instead of hardcoding in the BDA.

- Don't leak console input/output handles when opening them in BiosInitialize.
- Deinitialize the emulator in the reverse order it was initialized.
- Simplify VgaGetVideoBaseAddress and VgaGetVideoLimitAddress and use the former one in VgaTranslate[Read-Write]Address.
- Use only unicode Win32 APIs where it's needed.
