andre 25ae331e12 Link state change notification of ethernet media to the routing socket.
o Extend the if_data structure with an ifi_link_state field and
  provide the corresponding defines for the valid states.

o The mii_linkchg() callback updates the ifi_link_state field
  and calls rt_ifmsg() to notify listeners on the routing socket
  in addition to the kqueue KNOTE.

o If vlans are configured on a physical interface notify and update
  all vlan pseudo devices as well with the vlan_link_state() callback.
