Shut down part or all of a full-duplex connection.
If @shutdown_read is %TRUE then the receiving side of the connection
is shut down, and further reading is disallowed.
If @shutdown_write is %TRUE then the sending side of the connection
is shut down, and further writing is disallowed.
It is allowed for both @shutdown_read and @shutdown_write to be %TRUE.
One example where it is useful to shut down only one side of a connection is
graceful disconnect for TCP connections where you close the sending side,
then wait for the other side to close the connection, thus ensuring that the
other side saw all sent data.
