Fixes use-after-free bugs causing assertion failures at shutdown,
because all "abandoned" SocketEvents are still in the linked list.

1686f4e857 event/IdleMonitor: refactor to IdleEvent 
Instead of using this as a base class implementing a virtual method,
the new class IdleEvent can be used as a variable, decoupling
IdleMonitor's internal state from the derived class.

This is similar to commit 30a5dd267b
which refactored TimeoutMonitor to TimerEvent.
