Reimplement event objects with condition variables

This matches the intended semantics more closely. Every separate opened
copy is awakened once when the object is signaled. If the object is
opened another time, the new copy is awakened once if the object has
ever been signaled.

The previous version never cleared the event, which caused some issues
with the watchdog timer, among other things.
