be4f3cd0d9 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.

b07fbc17e9 Add Cisco Skinny Station protocol support to libalias, natd, and ppp.
Skinny is the protocol used by Cisco IP phones to talk to Cisco Call
Managers.  With this code, one can use a Cisco IP phone behind a FreeBSD
NAT gateway.

Currently, having the Call Manager behind the NAT gateway is not supported.
More information on enabling Skinny support in libalias, natd, and ppp
can be found in those applications' manpages.

01ba618f4a Don't pretend natd(8) doesn't work with ppp(8) interfaces.
While there's probably a better way to achieve the same,
nothing precludes us from using natd(8) on tun(4) links.

99150dfb78 I don't know what the MAINTAINER means in src/ part of FreeBSD.
I'll still be overseeing the changes that go into natd(8) and
will maintain it the way I see it, non-preventing for the rest
of developers.

I will re-ask for the MAINTAINER bit if the ${MAINTAINER} gets
defined.

3daff2423f Back out part of the revision 1.2 changes -- sendto(2) can
not return ENOBUFS for unreliable protocols like divert.

This should fix an issue when natd(8) keeps spamming already
full dummynet(4) queues with the same packet forever.

Avoid using parenthesis enclosure macros (.Pq and .Po/.Pc) with plain text.
Not only this slows down the mdoc(7) processing significantly, but it also
has an undesired (in this case) effect of disabling hyphenation within the

7731ee5af9 Back out both previous commits.
The first one got screwed up by me because of rev 1.33, which was
incorrectly merged into my patches by myself, and so Ruslan (maintainer)
asked me to back them out.

Ruslan was ok with the second one, but since it needs rework, it'll be
readded later, when it doesn't conflict with the backout of the first one.
