lib, irmd, irm: Add dif_config

This adds dif_config to the prototype, in which one is able to specify
the parameters a DIF should have. The bootstrap operation of an IPCP
takes this as parameter and is oblivious to whether it is a shim or a
normal IPCP. The dif_config struct is also correctly serialized and
deserialized and passed opaquely to the correct IPCP. This IPCP is in
charge of deserializing it correctly.
