This changes the initial connection negotiation to have the ei_connection_setup as the pre-existing object id 0. Once the client has sent all the data to set up the connection, the EIS implementation replies with a new object ID that is the ei_connection protocol object, i.e. the main object. This allows for version negotiation of our main protocol object.
