Big move of driver input stack to a Plug-and-Play model:

Browse source 
- mouclass:
  Do non buffered IO. The pointer move should be smoother.
  Search non Plug-and-Play drivers in registry, instead of using their device name.
- kbdclass:
  Full rewrite to support more than one keyboard.
  Use registry settings as specified in MSDN.
  (Info: kbdclass is now very similar to mouclass)
- i8042prt:
  Keep it as a non Plug-and-Play driver, but register it in DEVICEMAP registry key.
- USB controller:
  Enable USB keyboard/mouse

I may have broken support for serial mice, i'll add it back in a few days...
