description:
When a new connection arrives on a listening port, copy over the
value of the TCP_NODELAY socket option from the listener to the
newly connected connection. Agrees with how Linux & FreeBSD behave,
and goes more with the spirit of accept(2) creating a socket with
the same properties as the listener.

Analysis by Kevin Lahey. Closes PR 17616 by myself.
