 * Address family routines,
 * used in handling generic sockaddr structures.
 *
 * Hash routine is called
 *	af_hash(addr, h);
 *	struct sockaddr *addr; struct afhash *h;
 * producing an afhash structure for addr.
 *
 * Netmatch routine is called
 *	af_netmatch(addr1, addr2);
 * where addr1 and addr2 are sockaddr *.  Returns 1 if network
 * values match, 0 otherwise.
