ipcpd: normal: Establish N-1 management flows

This adds the intial implementation of establishing management N-1
flows between normal IPCPs. On calling fmgr_mgmt_flow, a management
flow will be setup to a certain destination IPCP. After flow
allocation, the fd is handed to the RIB manager. The flow manager also
listens for incoming flow requests. In case they are management flows,
they are handed to the RIB manager, otherwise to the FRCT.
