First version of a somewhat complete D-Bus server interface.  Also
change user/group name to "_mandos".

* debian/mandos.postinst: Rename old "mandos" user and group to
                          "_mandos"; create "_mandos" user and group
                          if none exist.
* debian/mandos-client.postinst: - '' -

* initramfs-tools-hook: Try "_mandos" before "mandos" as user and
                        group name.

* mandos (_datetime_to_dbus_struct): New; was previously local.
  (Client.started): Renamed to "last_started".  All users changed.
  (Client.started): New; boolean.
  (Client.dbus_object_path): New.
  (Client.check_command): Renamed to "checker_command".  All users
                          changed.
  (Client.__init__): Set and use "self.dbus_object_path".  Set
                     "self.started".
  (Client.start): Update "self.started".  Emit "self.PropertyChanged"
                  signals for both "started" and "last_started".
  (Client.stop): Update "self.started".  Emit "self.PropertyChanged"
                 signal for "started".
  (Client.checker_callback): Take additional "command" argument.  All
                             callers changed. Emit
                             "self.PropertyChanged" signal.

  (Client.still_valid): Bug fix: use "getattr(self, started, False)"
                        instead of "self.started" in case this client
                        object is so new that the "started" attribute
                        has not been created yet.
  (Client.IntervalChanged, Client.CheckerIsRunning, Client.GetChecker,
  Client.GetCreated, Client.GetFingerprint, Client.GetHost,

  (Client.GetAllProperties, Client.PropertyChanged): New.
  (Client.StillValid): Renamed to "IsStillValid".
  (Client.StartChecker): Changed to its own function to avoid the
                         return value from "Client.start_checker()".
  (Client.Stop): Changed to its own function to avoid the return value
                 from "Client.stop()".
  (main): Try "_mandos" before "mandos" as user and group name.
