Adjust EQ to support long events.

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.
