Joe Marcus Clarke 5c7e7e80cc Fix Skinny and PPTP NAT'ing after the introduction of the {ip,tcp,udp}_next
functions.  Basically, the ip_next() function was used to get the PPTP and
Skinny headers when tcp_next() should have been used instead.  Symptoms of
this included a segfault in natd when trying to process a PPTP or Skinny
packet.
