Gets changes in the two given (aka old and new) interface lists. Changes are resolved based on IP-addresses.

Parameters:

	netIfListOld	List of the old interfaces. It is changed!
	netIfListNew	List of the new interfaces. It is changed!
	netIfListAdded	List to store interfaces, which were in netIfListNew, but were not in netIfListOld. May be NULL.
	netIfListRemoved	List to store interfaces, which were in netIfListOld, but were not in netIfListNew.
