 // UDPSocket and UDPSocketClient represent a UDP socket and its client. The
 // typical flow of using the interfaces is:
 // - Acquire a UDPSocket interface pointer and set a UDPSocketClient instance.
 // - (optional) Set options which are allowed prior to Bind().
 // - Bind the socket.
 // - (optional) Set options which are allowed after Bind().
 // - Send / request to receive datagrams. Received datagrams will be delivered
 //   to UDPSocketClient.OnReceived().
