Log:
[NTVDM]: Implement few INT 33h (mouse) functions:
- For function 0Ah, we don't still support defining hardware cursor.
- Implement function 0Ch (define interrupt subroutine params), compatible MSMOUSE v1.0+
- Implement function 14h (exchange interrupt subroutines), compatible MSMOUSE v3.0+
- Implement function 18h (set alternate mouse user handler), that is the same thing as
function 0Ch but for a set of maximum 3 handlers, compatible MSMOUSE v6.0+
- Implement function 19h (return user alternate interrupt vector) that returns the handler
associated with a call mask, compatible MSMOUSE v6.0+
- Call all those handlers accordingly to their associated call mask, for mouse moves and
mouse button presses.
