* DBUS-API (se.recompile.Mandos.Client.LastCheckerStatus): New
                                                           property.
* mandos (Client.last_checker_status): Use -2 instead of None to match
                                       D-Bus property.  All users
                                       changed.
  (Client.checked_ok): Remove "timeout" argument and call
                       "self.bump_timeout()" instead.
  (Client.bump_timeout): New; separated out from "checked_ok".
  (ClientDBus.last_checker_status): Hook to a D-Bus property.
  (ClientDBus.LastCheckerStatus_dbus_property): New D-Bus property.
  (ClientHandler.handle): Call client.bump_timeout() instead of
                          client.checked_ok().
