This adds two new functions: `Conn::register_removal_hook()` and `Conn::unregister_removal_hook()` for registering a hook function to be called back during `connection_state_remove`. The benefit of using hook callback approach is better scalability: the overhead of unrelated protocols having to dispatch no-op `connection_state_remove` handlers is avoided.
