* plugins.d/mandos-client.c: An empty interface name now means to
                             autodetect an interface; to specify no
                             particular interface, use "none".
  (sys_class_net): New global variable for the "/sys/class/net" path.
  (good_interface): New function to determine the suitability of an
                    interface.  Used by a scandir() call in main().
  (main): Changed default value for "interface" to the empty string.
          Moved "connect_to" to be a global variable.  Only take down
          and up interface if its name is not "none".
* plugins.d/mandos-client.xml (OPTIONS): Update documentation for the
                                         "--interface" option.
