consistently use exit instead of return in main().
use LOG_WARNING instead of LOG_ERR for non critical errors.

Obtained from: NetBSD

Copy head@r302406 to stable/11 as part of the 11.0-RELEASE cycle.

Add META_MODE support.

Off by default, build behaves normally.
WITH_META_MODE we get auto objdir creation, the ability to
start build from anywhere in the tree.

Still need to add real targets under targets/ to build packages.

Make WARNS=6 the default for libexec/.

Just like bin/ and sbin/, I think setting WARNS to the highest value
possible will make it more attractive for people to fix warnings.

- The WARNS variable is set in the Makefile in the directory of the
application itself, making it more likely that it will be removed out
of curiosity to see what happens.
- New applications will most likely build with WARNS=6 out of the box,
because the author would more likely fix the warnings during
development than lower WARNS.

Unfortunately almost all apps in libexec require a lowered value of
WARNS.

Fix most cases where the address of an int is passed to a function expecting a
socklen_t * argument.

Port to TI/RPC and/or IPV6.

The .Nm utility

Spell void * as void * rather than caddr_t. This is complicated by the
fact that caddr_t is often misspelled as char *.

o __P removal
o use new style prototypes and function definitions
o signal handlers need an argument. Mark it unused.

Remove whitespace at EOL.

mdoc(7) police: removed HISTORY info from the .Os call.

- Backout botched attempt to intoduce MANSECT feature.
- MAN[1-9] -> MAN.

Set the default manual section for libexec/ to 8.

$Id$ -> $FreeBSD$

Do not terminate syslog() messages with a dot, as others daemons do.

Revert $FreeBSD$ to $Id$

Make the long-awaited change from $Id$ to $FreeBSD$

This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.

Correct some man page cross references and file location references.
