Subject: ipcpd: Revise internals of normal IPCP

This removes the RIB as a datastructure and CDAP as the protocol
between IPCPs. CDAP, the rib and related sources are deprecated. The
link-state protocol policy is udpated to use its own protocol based on
a simple broadcast strategy along a tree. The neighbors struct is
deprecated and moved to the library as a generic notifier component.
