[AD] [DOS] Win2k mouse bug

["Eric Botcazou" <ebotcazou@xxxxxxxxxx>]

Since no progress was made on the Win2k mouse bug, I think we could rely on
the user to select a proper mouse driver under WinNT 3.5x/4.0 and Win2k.

Here's the situation:
- the mickeys driver (driver #1) crashes under WinNT and works under Win2k,
- the int33h driver (driver #2) crashes under WinNT and doesn't work (but
doesn't crash) under Win2k,
- the polling driver (driver #3) works under WinNT and doesn't work (but
doesn't crash) under Win2k.

To make things as clear as possible, I'm proposing to add two specific
drivers: a WinNT 3.5x/4.0 specific driver (driver #4) and a Win2k specific
driver (driver #5) that are of course only wrappers for driver #3 and driver
#1 respectively.

The mouse driver won't never crash on any system if no driver is selected in
allegro.cfg; the patch is attached.
