Summary: Keep tcp connections alive

Initial Comment:
When retrieving a ftp file, curl do not ensure that the control socket is alive during time.

If one download a big file, the connection could be close close before completion : A firewall or a router has close the connection, because it seems inactive.

A common answer to this problem is to send "NOOP" command, in order to keep the connection up.

The attached patch, made against official curl 7.17.1, is a first attempt to get this feature into curl.

Would you please review it ?

I didn't know how to include it proprely with other options so I kept, for the moment, the timeout parameter directly in the function.

Regards,
