mixer(8): Style: Tag no-return usage() as __dead2

Coverity really should have figured this out from the exit(3) call at the end
of the routine, but just make it explicit.

No functional change.

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.

The last big commit: let usr.sbin/ use WARNS=6 by default.

mixer(8) is WARNS=6 clean since 1.25.

Tested with: 'make universe'

Fix a typo.

Clean up code and fix style(9) nits.

Update list of possible mixer devices. These devices were added to
soundcard.h more than ten years ago.

- Check device masks and bypass printing headers if capable device does
not exist. /etc/rc.d/mixer tried to restore non-existent recording
source because /var/var/db/mixer*-state contains '=rec' for example.
- Remove hardcoded mixer2 and mixer3 and do the right thing.
- Replace getopt(3) with hand-rolled option parser. It was not able
to handle 'mixer -rec mic' although it is a valid command.
- Make '-s' and '-S' mutualy exclusive as mixer(8) says.
- Do not re-read recording source unless it has been modified.

o Add "line" device to a list of mixer(8) devices.

- Fix possible memory leak due to repetetive strdup(3) without matching
free(3).
- print_recsrc() should honor shortflag and give appropriate output for
later consumption by /etc/rc.d/mixer. This will ensure that recording
device selections survived across reboot. Output everything to stdout
instead if stderr.

mdoc(7) police: do not split author names in the AUTHORS section.

Several cleanups:
- use getopt(3) to parse command line arguments instead of home-made incomplete
parser;
- be more verbose when error in command line encountered (i.e. incorrect
playing/recording device, incorrect recsrc syntax).

I've always wanted to be able to dump out the current values of
the mixer in a format suitable for saving and handing off to
mixer(1) at some future date to restore the settings.
Add a -s flag to do this.

Remove single-space hard sentence breaks. These degrade the quality
of the typeset output, tend to make diffs harder to read and provide
bad examples for new-comers to mdoc.

$Id$ -> $FreeBSD$

Add $Id$, to make it simpler for members of the translation teams to
track.

The Id line is normally at the bottom of the main comment block in the
man page, separated from the rest of the manpage by an empty comment,
like so;

.\" $Id$
.\"

If the immediately preceding comment is a @(#) format ID marker than the
the $Id$ will line up underneath it with no intervening blank lines.
Otherwise, an additional blank line is inserted.
