Inform other end of a connected socket that we're no longer
available. In general, this should be invoked before close()
The shutdown function shuts down the connection of the socket:
- stops receiving data for this socket. If further data
arrives, it is rejected.
- stops trying to transmit data from this socket. Also
discards any data waiting to be sent. Stop looking for
acknowledgement of data already sent; don't retransmit
if any data is lost.
