NAT PPTP Set-Link-Info

NAT PPTP Set-Link-Info messages in the PAC->PNS direction. These are sent by Windows Server 2003.

Note that Set-Link-Info messages do not need to be NATed in the PNS->PAC direction, since we never NAT the PAC call id.

Tested for linux-2.4.29 only, but should also apply to both 2.6 versions in patch-o-matic-ng.

Thanks, applied to the 2.4.x branch and merged into 2.6, 2.6.11 and netfilter-2.6.14.git.
