* plugins.d/mandosclient.c (start_mandos_communication): Changed
                                                        "if_index" to
                                                        be of type
                                                        "AvahiIfIndex".
                                                        All callers
                                                        changed.
 (main): Add default values to "interface" and "if_index".  Only
         change if_index from default if "interface" was given.

* server.py (IPv6_TCPServer.server_bind): Bug fix: test if interface
                                          is empty, not if equal to
                                          avahi.IF_UNSPEC.
  (if_nametoindex): Bug fix; typo: assign to _func[0], not func[0].
  (main): Bug fix: Do not set service.interface unless the interface
          setting has been given.

# This is not a problem, since cryptroot forces itself to run LAST.
