Summary:                    [patch] peer outboundproxy-ptr is copied to dialog
and then freed
Description: 
Hi,
create_addr() refs a peer (by using find_peer), copies the peer's
outboundproxy ptr to the dialog (create_addr_from_peer -> obproxy_get) and
then unrefs the peer.

While freeing the peer, the outboundproxy gets freed too, so as a result
the ptr in the dialog shows to unallocated memory. This results in
outboundproxy configured by peer not working.

---------------------------------------------------------------------- 
13700.patch worked for me. I did something similar in locking the peer
while the outboundproxy-ptr is in use, but did not post it yet, because I
had some problems with cancels and there via-tags not matching those of the
invite. But that seems to be another issue. I guess yours is matching the
chan_sip style more.
