Summary:                    [patch] SIP autocreate peers registered when request
to unregister
Description: 
When autocreate is enabled and a peer is *not* registered, and such a peer
sends a REGISTER message with the "Expires: 0" header (to indicate it wants
to unregister), the peer is apparently registered and then partially(?)
unregistered:
 * There is a NOTICE-level option poke message;
 * The sequence of PeerStatus manager events shows 3 events:
   1. Unregistered (that's expected)
   2. Registered (that's not)
   3. Reachable

Thank you, the patch totally fixed our problem!

I have been running a production server with the patch for 48 hours now.
Without it, we would have seen dozens of failures already (a monitor
program depends on registration notifications coming in correct order), and
there were none.
