Summary:                    [patch] fix SIP indicate deadlocks when lots of
state changes
Description: 
Running 1.8.2-rc1 and was able to deadlock several times during failed SIP
state change indications.  Found by testing 4 SIP phones in close proximity
and rapidly, yet manually, transferring blind, parking calls, picking them
up at another phone, etc.  Also, was using the Bridge() app for buddy
pickup purposes.

We're experiencing deadlocks on a production server (aprox once a day).
I'm attaching a core show locks, which imo seems to be related to this
issue, although we are not using hints.

If you could please confirm the relationship, I'll apply the patch today
and let you know if * stops freezing.
