During startup (and after every HUP signal) user land applications running the new libalias will try to read a file in /etc called libalias.conf: that file contains the list of modules to load. User land applications affected by this commit are ppp and natd: if libalias.conf is present in /etc you won't notice any difference. The only kernel land bit affected by this commit is ng_nat: if you are using ng_nat, and it doesn't correctly handle ftp/irc/etcetc sessions anymore, remember to kldload the correspondent module (i.e. kldload alias_ftp). General information and details about the inner working are available in the libalias man page under the section 'MODULAR ARCHITECTURE (AND ipfw(4) SUPPORT)'. NOTA BENE: this commit affects _ONLY_ libalias, ipfw in-kernel nat support will be part of the next libalias-related commit.

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. Make libalias WARNS?=6-clean.

I was hoping WARNS?=6 might reveal more serious problems, and perhaps the source of the -O2 breakage, but found no smoking gun.
