  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.
