Currently, datagram transports must report identical transport parameters in order to negotiate use of the datagram transport. This is not strictly necessary, they just need parameters that fit some notion of "compatability" (eg. both ends share some mutually-supported version of the datagram protocol). This change allows datagram transports to implement their own notion of compatible transport parameters, by adding a SetRemoteTransportParameters method to DatagramTransportInterface which checks if the remote parameters are compatible with the local endpoint and returns an error if they are not.
