Note: Skinny support is not enabled in natd or ppp by default.

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.

Use them consistently throughout libalias to a) reduce code duplication, b) improve code legibility, c) get rid of a bunch of alignment warnings.
