* NameOwnerChanged handling
*
* Some services we provide allow an application to register for
* a signal that it needs. While it can also unregister, we must
* be prepared for the case where the application simply crashes
* and thus doesn't clean up properly. The way to handle this in
* DBus is to register for the NameOwnerChanged signal which will
* signal an owner change to NULL if the peer closes the socket
* for whatever reason.
*
* Handle this signal via a filter function whenever necessary.
* The code below also handles refcounting in case in the future
* there will be multiple instances of this subscription scheme.
