RawSocketOption class

The RawSocketOption is used as a parameter to Socket.setRawOption and RawSocket.setRawOption to customize the behaviour of the underlying socket.

It allows for fine grained control of the socket options, and its values will be passed to the underlying platform's implementation of setsockopt and getsockopt.
