 * 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.
