ipcpd: Remove FRCT from normal IPCP
In order to ensure 100% reliable transfer, the protocol state machine that takes care of retransmission and SDU ordering has to be in the application. Flow allocation in the normal now uses fds. The PDU_type field was deprecated and AE's within the DIF can use reserved fds.
