Nick Mathewson 232055ef49 Tweak patch for event_base_foreach_event()
* Fix whitespace
* Explain return value from callback function
* Reinstate return value so that caller can tell whether forech
  exited early.
* Rename event_base_foreach_event_() to
  event_base_foreach_event_nolock_().
* Use event_base_foreach_event_cb_fn typedef in more places
* Be more dire about undefined behavior.
