* plugins.d/mandos-client.c (get_flags): Don't clobber errno.
  (up_interface): Removed; replaced with "interface_is_up".
  (interface_is_up, interface_is_running,
   lower_privileges_permanently, take_down_interface): New.
  (bring_up_interface): Return "error_t".  Use new functions
                        "interface_is_up", "get_flags", and
                        "interface_is_running".
  (main): Save all interfaces either autodetected or specified with
          --interface in argz vector "interfaces".  Save interfaces to
          take down on exit in argz vector "interfaces_to_take_down".
          Save interface names for DEVICE variable to network hooks as
          argz_vector "interfaces_hooks".  Bug fix: Be privileged
          while stopping network hooks.
* plugins.d/mandos-client.xml (SYNOPSIS): Changed --interface synopsis.
  (DESCRIPTION): Updated to document use of all interfaces.
  (OPTIONS): Updated description of "--interface".
