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.

Lock down with WFORMAT?=1, with overrides in the subdirectories which
are not yet warning-clean. Tested on i386 and alpha.

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

$Id$ -> $FreeBSD$

Revert $FreeBSD$ to $Id$

Added:
ic=expect/send script modem init script
ac=expect/send script modem answer script
ct#val chat script timeout (seconds)
rt#val recycle timeout (seconds) if 'ac' set
dc#val debug bitmask for debugging chat scripts
hw (boolean) enable crtscts handshaking
if=path 'issue' file sent prior login prompt

chat.c is a simplistic expect/send chat module.

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.

Finally commit the changes that make getty(8) no longer depend on the
COMPAT_43 cruft. This is supposedly the last core utility that has
been using it! (So now, one should be able to remove this option from
the config files. Be aware that the last officially released xterm
however still requires it.)

The getty has been running now for several weeks on my modem line, so
i feel safe about it.

Replace this with the 1.1.5.1 getty. David says that the 4.4 version is too
broken to live.

Implement fbtab ala SunSO.
Could not compile it (on thud) because ttychar.h was still broken.

Update to new make macros and disable Kerberos because we haven't got it
set up right yet.
