This adds support for the TCP_NODELAY socket option for lwIP sockets.
Generally, TCP sockets use the Nagle algorithm and will send data when
an ACK is received or after all previously-sent data has already been
ACKed.
If the TCP_NODELAY option is set for a socket, every write to the socket
will trigger a packet to be sent.
