SIP Dialog ref counting
This patch adds reference counting for sip dialogs into 1.6.0.
When proc_session_timer() is called from the scheduler thread
it has no guarantee the session timer's dialog won't be freed
from underneath it. Now the session timer holds a reference
to the dialog, preventing it from being destroyed during the
middle of proc_session_timer().
(closes issue #13623)
