Review request for Asterisk Developers.


Changes
-------

This update address's all the reviewboard comments so far except for the one Russell pointed out about the event thread blocking while sending out the registrations.  I'm still thinking about that.


Summary
-------

The res_stun_monitor module monitors the perceived external ip/port provided by a STUN server and sends out an event when that perceived ip/port changes in any way.  This patch adds chan_sip and chan_iax as listeners to this event.  Both of these channel drivers react to the event by regenerating all outbound registers in order to alert the endpoints being registered with to the new address location.  This feature's primary use case is when Asterisk is behind a NAT in which the external ip address is dynamic or the port mappings of the NAT device are subject to change.

I will update the CHANGES file before committing this.  That is not included within this review though.

Testing
-------

I tested all the res_stun_monitor.conf options to verify functionality.
I tested the channel driver's event listening by triggering an address change and verifying registrations are sent via wireshark.


Thanks,

David
