Update linked() for OSPFv3.
A router vertex w has a point-to-point link back to a router
vertex v if v's router ID occurs as neighbour ID in one of the
point-to-point links described in w's router LSA.
A router vertex w has a link back to a network vertex v if the router
ID of v's advertising router (i.e. DR) occurs as neighbour ID in one
of the transit links described in w's router LSA, and v's interface
ID to the network matches the neighbour interface ID of that transit
link.
A network vertex w has a link back to a router vertex v if v's router
ID occurs in the list of attached routers in w's network LSA.
Also, get_rtr_link() and get_net_link() take an unsigned int now.
