"ip forwarding" command.

[Jim Crumpler]

Hi, there is a command for "no ip forwarding", but the "ip forwarding"
command seems missing..  Here's a preliminary patch..

I noticed these commands don't "stick" in the config.. Do they need to be
moved to rib.c where the install_node is for ip?

One last comment - would it not be better to replace "[no] ip forwarding"
with the Cisco style "[no] ip routing"?

Jim..
