Summary:                    [patch] IAXy runs ok for a while, then goes bonkers
Description: 
After up to a month, or as little as a day or two, both the IAXy I
originally purchased, and a replacement given to me by Stephen Burcham in
October (to try to eliminate a specific piece of hardware) become
unreliable.  In some cases it just stops processing calls, in the more
likely case, documented in the attached log, it goes into a
reachable/unreachable loop like this:

[Dec  9 10:01:45] NOTICE[26712]: chan_iax2.c:8832 __iax2_poke_noanswer:
Peer 'x29' is now UNREACHABLE! Time: 5
[Dec  9 10:01:45] NOTICE[26712]: chan_iax2.c:7912 socket_process: Peer
'x29' is now REACHABLE! Time: 10
[Dec  9 10:02:29] NOTICE[26712]: chan_iax2.c:8832 __iax2_poke_noanswer:
Peer 'x29' is now UNREACHABLE! Time: 10
[Dec  9 10:02:29] NOTICE[26712]: chan_iax2.c:7912 socket_process: Peer
'x29' is now REACHABLE! Time: 13

Since it provides service to the phone next to the main place at which
"she who expects phones to work" generally sits, this causes me a major
headache.

---------------------------------------------------------------------- 
I've discovered a related separate problem.  Every restart of asterisk
causes asterisk to reprovision the IAXy with provisioning version
"1624236442".  The IAXy accepts this, and from then on the IAXy responds to
REGACKs with INVAL.

Submitting an IAX2 PROVISION command causes Asterisk to offer up both
provisioning version "1624236442" and "3538259848" to the IAXy.  By issuing
the IAX2 PROVISION command several times, it's possible to get the IAXy to
accept version "3538259848".  Only after this is everything "ok".

I'm debugging this now.  To assist in this, I needed to add the ability to
put "debug=yes" into iax.conf, a useful feature that some other modules
have.  I'm uploading a patch to trunk which implements this.
