Create work around for scheduler leaks during shutdown.

Browse Source 
* Added ast_sched_clean_by_callback for cleanup of scheduled events
  that have not yet fired.
* Run all pending peercnt_remove_cb and replace_callno events in chan_iax2.
  Cleanup of replace_callno events is only run 11, since it no longer
  releases any references or allocations in 13+.
