This change adds reliability for Ethernet trunks built with ng_one2many:

- Introduce another ng_ether(4) callback ng_ether_link_state_p, which
  is called from if_link_state_change(), every time link is changed.
- In ng_ether_link_state() send netgraph control message notifying
  of link state change to a node connected to "lower" hook.
