Raise WARNS for various tools where possible.

Submitted by: Marius Nünnerich <marius@nuenneri.ch>

style.Makefile(5):
Use WARNS?= instead of WARNS=.

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.

Default to WARNS=2.
Binary builds that cannot handle this must explicitly set WARNS=0.

Upgrade (almost) to natd 2.0b1

- Transparent proxy support.
- PERMANENT_LINK IS NOW OBSOLETE, use redirect_port instead.
- Drop support for early FreeBSD 2.2 versions
- If separate input & output sockets are being used
use them to find out packet direction instead of
normal mechanism. This can be handy in complex environments
with multiple interfaces.
- PPTP redirect support by Dru Nelson <dnelson@redwoodsoft.com> added.
- Logging enhancements from Martin Machacek <mm@i.cz> added.

This commit was generated by cvs2svn to compensate for changes in r26781,
which included commits to RCS files with non-trunk default branches.

Bring natd into main source tree now that the
pppd/natd combination works ok.
