Summary:                    Registrations persist after removal and sip reload
Description: 
I have a registry entry in sip.conf, like:

 register => 4550607774:hiddenpassword at 10.10.44.100/4550607774

and that has been registered for a while.

Then I remove that entry from sip.conf and issue sip reload, expecting the
registry entry to go away. It does indeed disappear from sip show registry
after the sip reload, but then I get:

WARNING[24870]: chan_sip.c:16334 handle_response_register: Got 200 OK on
REGISTER, but there isn't a registry entry for '4550607774' (we probably
already got the OK)

When I tcpdump I can see that more attempts at registration are sent for
that peer.

  SIP registry ref count error
  
  During a sip reload, the list of sip_registry objects are
  supposed to be traversed, unlinked, and destroyed, but
  destruction never takes place due to a ref counting error.
  This causes a memory leak when registry items are removed
  from sip.conf and reloaded.  While the registries are removed
  from the global list, they are not removed from the scheduler.
  Because of this, SIP register attempts continue to be sent
  out for the item even though it may no longer be in the .conf.
