* plugins.d/password-request.c (init_gnutls_global): Renamed
                               "pubkeyfile" to "pubkeyfilename" and
                               "seckeyfile" to "seckeyfilename".
  (combinepath): Changed to use asprintf instead of malloc and memcpy.

  (main): Renamed "pubkeyfile" to "pubkeyname", renamed "seckeyfile"
          to "seckeyname" and created new non-const variables
          "pubkeyfilename" and "seckeyfilename".

* mandos (AvahiService.__init__): Bug fix: initialize
                                  "self.max_renames".
  (AvahiService.rename): Bug fix: use "self.name" instead of "name".
