tipc: Remove obsolete comments about routing table updates

/*

 * Routing table management - five cases to handle:

 *

 * 1: A link towards a zone/cluster external node comes up.

 *    => Send a multicast message updating routing tables of all

 *    system nodes within own cluster that the new destination

 *    can be reached via this node.

 *    (node.establishedContact()=>cluster.multicastNewRoute())

 *

 * 2: A link towards a slave node comes up.

 *    => Send a multicast message updating routing tables of all

 *    system nodes within own cluster that the new destination

 *    can be reached via this node.

 *    (node.establishedContact()=>cluster.multicastNewRoute())

 *    => Send a  message to the slave node about existence

 *    of all system nodes within cluster:

 *    (node.establishedContact()=>cluster.sendLocalRoutes())

 *

 * 3: A new cluster local system node becomes available.

 *    => Send message(s) to this particular node containing

 *    information about all cluster external and slave

 *     nodes which can be reached via this node.

 *    (node.establishedContact()==>network.sendExternalRoutes())

 *    (node.establishedContact()==>network.sendSlaveRoutes())

 *    => Send messages to all directly connected slave nodes

 *    containing information about the existence of the new node

 *    (node.establishedContact()=>cluster.multicastNewRoute())

 *

 * 4: The link towards a zone/cluster external node or slave

 *    node goes down.

 *    => Send a multcast message updating routing tables of all

 *    nodes within cluster that the new destination can not any

 *    longer be reached via this node.

 *    (node.lostAllLinks()=>cluster.bcastLostRoute())

 *

 * 5: A cluster local system node becomes unavailable.

 *    => Remove all references to this node from the local

 *    routing tables. Note: This is a completely node

 *    local operation.

 *    (node.lostAllLinks()=>network.removeAsRouter())

 *    => Send messages to all directly connected slave nodes

 *    containing information about loss of the node

 *    (node.establishedContact()=>cluster.multicastLostRoute())

 *
