Motiviation: Because of how we implemented the registration / deregistration of an EventLoop it was not possible to wrap an EventLoop implementation and use it with a Channel. Modification: - Introduce EventLoop.Unsafe which is responsible for the actual registration. - Move validation of EventLoop / Channel combo to the EventLoop - Add unit test that verifies that wrapping works Result: Be able to wrap an EventLoop and so add some extra functionality.
