Handle secondary DNS correctly for 3G

Switch over to handling DNS from ppp.linkup allowing mulitple 3G cards to coexist on the same box

Add ppp endpoints IP as gateway

Add and use ppp-script

Remove ftp-proxy/pftpx/ftpsesame references we handle all of this in kernel now.(yay!)

Correctly set old wan ip

Set /tmp/rc.newwanip_oldip

Remove bogus commands that adds a route to the new address pointing to dhcp.
It seems uncertain either to be a typo of $new_ip_address and $old_ip_address my test show that either cases it does more harm than good.

For now remove it altogether since it causes strange issues and makes ipsec tunnels not work on the interface with the new address.

DHCP Renew does "too much"

Ticket #1260
