From: Ricardo Labiaga <Ricardo.Labiaga@xxxxxxxxxx>
Follow the model we use in the client. Make the sequence arguments
part of the regular RPC arguments. None of the callbacks that are
soon to be implemented expect results that need to be passed back
to the caller, so we don't define a separate RPC results structure.
For session validation, the cb_sequence decoding will use a pointer
to the sequence arguments that are part of the RPC argument.
