events (also filters and handlers) now have reference counting.
Add reference counting to events, event filters and event handlers so they can recurse main loops. Note that the required "continuation" when entering main loops is not there, thus recursion will restart and this will fail badly in lots of cases. This should be fixed in future commits.
