Spelling fixes for libexec/

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.

Sync program's usage() with manpage's SYNOPSIS.

Mechanically kill hard sentence breaks.

Fix typos; each file has at least one s/seperat/separat/
(I skipped those in contrib/, gnu/ and crypto/)
While I was at it, fixed a lot more found by ispell that I
could identify with certainty to be errors. All of these
were in comments or text, not in actual code.

pollution from <strings.h>.

o register removal

mdoc(7) police: remove extraneous .Pp before and/or after .Sh.

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

Set the default manual section for libexec/ to 8.

mdoc(7) police: use the new features of the Nm macro.

Don't call err() without a format string.

$Id$ -> $FreeBSD$

.Sh AUTHOR -. .Sh AUTHORS. Use .An/.Aq.

Use warn(3). Hardcode progname instead of using argv[0]. Use Pa for file
name.

Many places in the code NULL is used in integer context, where
plain 0 should be used. This happens to work because we #define
NULL to 0, but is stylistically wrong and can cause problems
for people trying to port bits of code to other environments.

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.

Sort cross references.

Close PR #2193: support backslash line continuations.
(Also did some minor cleanups.)

Use err() instead of perror()/exit() and remember to #include <errno.h>
and <err.h>.

Small touchups:

- Fix typos in comments in hash.c.
- Remove unneeded and unused member from grouplist struct in hash.h.
(Curiously, the compiler never complained about this even though the
member was of type 'struct grps' which is not defined anywhere in
this program.)
- char ch -> int ch in revnetgroup.c.
- char *argv[0]; -> char *argv[]; also in revnetgroup.c.
- Force the user to specify at least one of the -u or -h flags
and complain if they specify both.
