udp/session: refactor to support dgram mode
- adds session layer support for datagram based protocols - updates udp to work in pure connectionless and datagram mode. The existing connected mode is now 'accessible' for apps as a dummy UDPC, as in, connected udp, protocol. - updates udp_echo, echo client, echo server code to work in datagram mode.
