Copy head to stable/9 as part of 9.0-RELEASE release cycle.

Include gettytab.h before extern.h so that the declarations of struct
gettyflags, gettynums and gettystrs are available.

o __P removal
o remove register
o use strict prototypes

Changed setflags() to set_flags(). This fixes world breakage due to
recently incremented namespace pollution in <unistd.h>.

$Id$ -> $FreeBSD$

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.
