it is thus the job of the proxy, not the registrar, to remove the
currently unusable registration.  the proxy could do it either by
sending un-REGISTER request to registrar or via an mi/rpc command.  the
former is possible now.  the latter requires that instance and reg_id
params are added to ul_rm_contact mi command.
