Revert r330897:

This was intended to be a non-functional change. It wasn't. The commit
message was thus wrong. In addition it broke arm, and merged crypto
related code.

Revert with prejudice.

This revert skips files touched in r316370 since that commit was since
MFCed. This revert also skips files that require $FreeBSD$ property
changes.

Thank you to those who helped me get out of this mess including but not
limited to gonzo, kevans, rgrimes.

MFC r323252:

Add a new getty/gettytab capability to generate an initial message dynamically.

This modification adds a new gettytab(5) option (iM) to specify a
program to run that will generate the initial (banner) message that is
displayed before the login prompt. Such a capability is useful when
dynamic information is needed in the banner message that cannot be
supplied by the set of % substitution sequences available in the "im"
option.

Spelling fixes for libexec/

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

- Use the initial terminal mode instead of the current mode
as the source of defaults for terminal device parameters.

- Do duplucate code reduction and simplification enabled by
the above.

Add a new gettytab(5) option - `pl', which if set tells getty that the line
in question is PPP-only line, i.e. no PPP-sequence detection is necessary and
PPP login program referenced by `pp' should be started automatically instead of
login(1)

Add 'df' string to gettytab - the strftime(3) format for %d
in the banner messages (of course, defaults to "%+").

Add 'nc' flag to gettytab -- no carrier. Forces non-blocking open and
setting of CLOCAL. Necessary for 3 wire RS-232 setups with dumb
terminals.

$Id$ -> $FreeBSD$

Add an 'al' (autologin username) capability to getty/gettytab. This is a
damn useful thing for using with serial consoles in clusters etc or secure
console locations. Using a custom gettytab entry for console with
an entry like 'al=root' means that there is *always* a root login ready on
the console. This should replace hacks like those which go with conserver
etc. (This is a loaded gun, watch out for those feet!)

Correct incompletes .Xrs. Remove duplicate #includes and unused variables.

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.

Add a new 'de' capability, specifying a number of seconds to sleep before
emitting the initial prompt.

This is useful in a number of circumstances :
- you have (a) stupid modem(s) that assert(s) DCD too soon.
- you have dialin users with stupid diallers and poorly
written chatscripts. (esp. some Winsock diallers)

BSD/OS also has this capability.

Add the >optional< ability to sense PPP link bringups and call an authentication program

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
