Permit reconnects

If a peer router has sent DEL msgs with the BYE flag set,
set the peer state to CLOSED and increment ep->need_connect.
We will again attempt to connect as needed.
Peer routers are option in the config file

It is okay to only have as and subnet for a device description
in the ccir_config file. Router is optional because this router
might not need to router through this subnet (i.e. it is a leaf
router).
Pass values rather than RIR to add router

Prepare to add the local router to the topology info.
The router does not send a RIR to itself.
