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.
