Summer of Code 2005: improve libalias - part 1 of 2
With the first part of my previous Summer of Code work, we get:
-made libalias modular:
-support for 'particular' protocols (like ftp/irc/etcetc) is no more hardcoded inside libalias, but it's available through external modules loadable at runtime
-modules are available both in kernel (/boot/kernel/alias_*.ko) and user land (/lib/libalias_*)
-protocols/applications modularized are: cuseeme, ftp, irc, nbt, pptp, skinny and smedia
-added logging support for kernel side
-cleanup
After a buildworld, do a 'mergemaster -i' to install the file libalias.conf in /etc or manually copy it.
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.

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.

Introduce inline {ip,udp,tcp}_next() functions which take a pointer to an {ip,udp,tcp} header and return a void * pointing to the payload (i.e. the first byte past the end of the header and any required padding). 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. This mostly involves renaming variables named link, foo_link or link_foo to lnk, foo_lnk or lnk_foo, fixing signed / unsigned comparisons, and shoving unused function arguments under the carpet.
I was hoping WARNS?=6 might reveal more serious problems, and perhaps the source of the -O2 breakage, but found no smoking gun.

Run through indent(1) so I can read the code without getting a headache. The result isn't quite knf, but it's knfer than the original, and far more consistent.

Mostly mechanical rework of libalias:
Makes it possible to have multiple packet aliasing instances in a single process by moving all static and global variables into an instance structure called "struct libalias".
Redefine a new API based on s/PacketAlias/LibAlias/g
Add new "instance" argument to all functions in the new API.
Implement old API in terms of the new API.

A significant rewrite of PPTP aliasing code.
PPTP links are no longer dropped by simple (and inappropriate in this case) "inactivity timeout" procedure, only when requested through the control connection.
It is now possible to have multiple PPTP servers running behind NAT. Just redirect the incoming TCP traffic to port 1723, everything else is done transparently.
Problems were reported and the fix was tested by: Michael Adler <Michael.Adler@compaq.com>, David Andersen <dga@lcs.mit.edu>

- Do not modify Peer's Call ID in outgoing Incoming-Call-Connected PPTP control messages.
- Cosmetics: replace `GRE link' with `PPTP link'.

Added true support for PPTP aliasing. Some nice features include:
- Multiple PPTP clients behind NAT to the same or different servers.
- Single PPTP server behind NAT -- you just need to redirect TCP port 1723 to a local machine. Multiple servers behind NAT is possible but would require a simple API change.
- No API changes!
For more information on how this works see comments at the start of the alias_pptp.c.
PacketAliasPptp() is no longer necessary and will be removed soon.
