<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">Should it? That seems a bit odd - if I have in my config file:
stunaddr =>
I would expect that to be a configuration error, not a request to not have STUN monitoring. At the very least, it seems that would make the "stunservermonitor" parameter redundant (also, if blank is acceptable but turns off STUN monitoring, that should be noted in the config file)</pre>

<pre style="margin-left: 1em; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">If I did not make an empty value disable STUN monitor then there would be no way to disable STUN monitoring short of a reload with no stunaddr listed. Previously, the STUN monitor was disabled by giving a bogus address. The dnsmgr API does not indicate if you gave it an unresolvable address so I could not do the same thing without redundant code.
The stunservermonitor parameter enables refreshing the DNS address of the STUN server. It does not affect if the STUN monitoring is enabled. Have you a better name?</pre>

Keeping the STUN socket always open will cause the STUN monitor to fail if
the STUN server address or our own address changes.
* Fix the reverse problem of the STUN server address changing after the
initial DNS resolution by using the dnsmgr to refresh the DNS resolution.
However, refreshing the DNS resolution may not be desireable for all
cases, as a result the stunservermonitor option is added to enable this.
* Fix ast_stun_request() return value consistency.
