Rename some classes in ProcessWindows. 

Renamed monitor -> driver, to make clear that the implementation here
is in no way related to that of other process plugins which have also
implemented classes with similar names such as DebugMonitor.

Also created a DebugEventHandler interface, which will be used by
implementors to get notified when debugging events happen in the
inferiors.
