Add some missing code to convert_real_interface_to_friendly_interface_name. There is no need to go through all the interfaces just to find out if an interface has a gateway or not and is the same for finding the real interface name of a friendly interface.

Use require_once instead of require, in case these files have been loaded previously. Fixes #631

Return the gateway status only for gateways apinger knows about instead of assuming that all gateways are down, which might give consecuences. Also prepend 'filter_' to the function used to kill states for down gateways in filter.inc to be consistent.
