 // UDPSocket and UDPSocketReceiver represent a UDP socket and its client. The
 // typical flow of using the interfaces is:
 // - Acquire a UDPSocket interface pointer.
 // - (optional) Set options which are allowed prior to Bind()/Connect().
 // - Bind or connect the socket.
 // - (optional) Bind the UDPSocketReceiver request returned by Bind()/Connect()
 // - (optional) Set options which are allowed after Bind()/Connect().
 // - Send / request to receive datagrams. Received datagrams will be delivered
 //   to the bound receiver's OnReceived() call.
