Subject: tools: Add tool to connect IPCP components

This enables user-written tools to instruct IPCPs to establish and
tear down connections (a.k.a. adjacencies) between its internal
components (Management and Data Transfer).

For more info, do "irm ipcp connect" or "irm ipcp disconnect" on the
command line.

This commit exposes a deletion bug in the RIB where FSO's fail to
unpack/parse. This will be fixed when the RIB is deprecated.
