Needed infrastructure for DHCP:

Corrected adapter index problem in iinfo.c.  Now the index returned is from
 IF->Index.
ninfo: ditto.
ip.c: Expose IPAddInterfaceRoute and IPRemoveInterfaceRoute for use by
 set ip address IOCTL.
if.c: Allow deleting of TCP context.
main.c: Turn off debugging in CVS.
