There are three CLI commands to stop and restart Asterisk each.

1) core stop/restart now - Hangup all calls and stop or restart Asterisk.
New channels are prevented while the shutdown request is pending.

2) core stop/restart gracefully - Stop or restart Asterisk when there are
no calls remaining in the system.  New channels are prevented while the
shutdown request is pending.

3) core stop/restart when convenient - Stop or restart Asterisk when there
are no calls in the system.  New calls are not prevented while the
shutdown request is pending.

ARI has made stopping/restarting Asterisk more problematic.  While a
shutdown request is pending it is desirable to continue to process ARI
HTTP requests for current calls.  To handle the current calls while a
shutdown request is pending, a new committed to shutdown phase is needed
so ARI applications can deal with the calls until the system is fully
committed to shutdown.

* Added a new shutdown committed phase so ARI applications can deal with
calls until the final committed to shutdown phase is reached.

* Made refuse new HTTP requests when the system has reached the final
system shutdown phase.  Starting anything while the system is actively
releasing resources and unloading modules is not a good thing.

* Split the bridging framework shutdown to not cleanup the global bridging
containers when shutting down in a hurry.  This is similar to how other
modules prevent crashes on rapid system shutdown.

* Moved ast_begin_shutdown(), ast_cancel_shutdown(), and
ast_shutting_down().  You should not have to include channel.h just to
access these system functions.
Extended the final shutdown phase sleep so I could send a HTTP request
while in the final shutdown phase.  The HTTP request was not refused while
the shutdown request was pending and refused after the final shutdown
phase was reached.
