Summary: In-dialog request clobbers Dialog module timer value

Initial Comment:
The dlg_onroute() callback invokes update_dlg_timer() when a "sequential 
request is successfully processed." There are two problems with this:

1 - It defeats the purpose of using the dialog timeout as a watchdog to limit 
call duration. Does it make sense to optionally suppress updates to the dialog 
timer? 

2 - the timer is updated with a value read from the timeout AVP. Unfortunately, 
the AVP is at best only transaction stateful, and thus (generally) undefined 
for sequential requests. As a result, the default timeout parameter is used 
instead (12 hours by default). Presumably the value from the timeout AVP needs 
to be cached in dialog-persistent memory for this to work as might be expected.

This problem exists in versions 1.2 through HEAD. Cheers,

This problem combined with the change from rev 2981 (call callbacks for
sequential ACKs) incorrectly resets the dialog timeout value for items in
the Session Timer module and the Bye2Bye patch.
