> When an event is scheduled, it often includes data with a reference bump for the scheduler.  If the scheduler context needs to be destroyed before all events have run, references are leaked.
> 
> This change adds a procedure to run all events that were scheduled for a specific callback, but haven't run yet.  chan_iax2 is modified to use this new procedure to run all pending peercnt_remove_cb and replace_callno events.
> 
> In the long run I think the scheduler will need to be ao2 aware, but that's not feasible for existing releases.
