Add RawDeviceEvent (pointers only for now). This commit changes the event queue to use EventLists instead of xEvent arrays. Only EQ is affected, event delivery still uses xEvent* (look for comment in mieqProcessInputEvent). RawDeviceEvents deliver driver information to the client, without clipping or acceleration.
