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.

---------------------------------------------------------------------- 
Since the private is locked in sip_set_rtp_peer, this looks like the right
fix. Several calls to sip_set_rtp_peer from remote_bridge_loop have the
channels locked, but then others do not.
