RawDatagramSocket class Null safety

An unbuffered interface to a UDP socket.

The raw datagram socket delivers the datagrams in the same chunks as the underlying operating system. It's a Stream of RawSocketEvents.

Note that the event RawSocketEvent.readClosed will never be received as an UDP socket cannot be closed by a remote peer.

It is not the same as a POSIX raw socket.
