	* connected.{c,h}: Include memory.h
	  (connected_add_ipv4) Use MTYPE for ifc label.
	  (connected_add_ipv6) Also should accept label. Store it in ifp.
	  (connected_del_ipv4) Taking label as argument is pointless.
	* rt_netlink.c: (netlink_interface_addr) update label usage
	  for connected_{add,delete} functions.
	* if_ioctl.c: (if_getaddrs) NULL label for connected_add_ipv6.
	* if_ioctl_solaris.c: (interface_list_ioctl) Pass LIFC_NOXMIT
	  so we also find out about NOXMIT interfaces like VNI.
	  Bit of hackery to turn interface names into the primary
	  interface name, later with routing socket messages we only
	  will about primary interfaces anyway, so we must normalise
	  the name.
	  (if_get_addr) take label as argument, so it can
	  be passed to connected_add.
	  If label is provided, then it is interface name to issue the
	  ioctl for address information on, not the ifp name.
	  (interface_list) List AF_UNSPEC too, just in case.
	* if_proc.c: (ifaddr_proc_ipv6) label for connected_add_ipv6.
	* interface.c: (if_addr_wakeup) Some very bogus code - sets
	  IFF_RUNNING - add comment.
	  (if_refresh)
	  (ip_address_install) Use MTYPE for ifc label.
	* ioctl_solaris.c: (if_mangle_up) New function. Hackery to make
	  IFF_UP reflect whether any addresses are left on the
	  interface, as we get signalled for IFF_UP flags change on the
	  primary interface only. Logical interfaces dont generate
	  IFINFO, but we do get an RTM_DELADDR.
	  (if_get_flags) Call if_mangle_up before return.
	* kernel_socket.c: (ifam_read) Fixup calls to
	  connected_{add,delete} to match above changes. Rename gate
	  variable to brd, less confusing.
	  Pass the interface name as a label, if it is not same name
	  as ifp->name.
