[kamailio] UAC module - registration not retried if there is no response to request (#149)

Please refer to closed issue #124.
Problem not solved... still seeing "stuck" registrations. Note that in this
case, I'm not getting a timeout response back from the UAS. The case where I'm
seeing the issue is when the UAS never responds at all.
I don't think adding the line to reset UAC_REG_ONGOING and UAC_REG_AUTHSENT at the
error: label really changed anything, since the done: label, which immediately follows it,
already reset those flags (and would be executed on the goto error).

Indeed, the flag would be reset via done label, I overlooked there is no return for error
label.
The same callback should be called when there is a local timeout. Do you get in the logs
an error message like:
```
... got sip response 408 while registering ...
```

In order to reproduce the issue, I added a firewall rule to drop the response from the
UAS. I saw the 'got sip response 408 while registering' message in the log and the
flags were reset, so there must be some other rare condition which is causing the flags to
get stuck in UAC_REG_ONGOING. This seems to occur once every few days (with registration
being done approximately every 60 to 90 seconds), and even sometimes up to a week before
I've seen the problem reoccur. I'll try to catch the next occurrence, and see what
information is in the log when it occurs.

Can you check if you had any error related to shared memory, like "no more
shm"?
I found a place where the flag was set and error with shm allocation would have left it
set. I pushed a patch for it in master branch.

I didn't save a copy of the logs from the last occurrence. I've been
waiting for the issue to occur again so I can gather more information, but,
of course, now that I want it to happen, it hasn't occurred over the last 5
days. I'll keep monitoring it and reply once it finally does occur again.

Closing this one for the moment, re-open if it appears again and you have more details.
