netlabel: Add a generic way to create ordered linked lists of network addrs
Create an ordered IP address linked list mechanism similar to the core kernel's linked list construct. The idea behind this list functionality is to create an extensibile linked list ordered by IP address mask to ease the matching of network addresses. The linked list is ordered with larger address masks at the front of the list and shorter address masks at the end to facilitate overriding network entries with individual host or subnet entries.
