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.

MFC r313107 (by danfe):
Try to fix the old "he capability is stupid" bug in gettytab(5)/getty(8)

There is one capability explicitly documented in gettytab(5) as stupid: he.
And it is indeed. It was meant to facilitate system hostname modification,
but is hardly usable in practice because it allows very limited editing
(e.g., it depends on a particular hostname length, making it non-generic).

Replace it with simple implementation that treats ``he'' as POSIX extended
regular expression which is matched against the hostname. If there are no
parenthesized subexpressions in the pattern, entire matched string is used
as the final hostname. Otherwise, use the first matched subexpression.
If the pattern does not match, the original hostname is not modified.

Using regex(3) gives more freedom, does not complicate the code very much,
and makes a lot more sense, in turn making ``he'' less stupid and actually
useful (e.g., it is now possible to obtain node or domain names from the
original hostname string, without knowing it in advance).

mdoc: drop redundant .Pp and .LP calls

They have no effect when coming in pairs, or before .Bl/.Bd

Sort sections.

Improve the manpage language a bit.
A PPP login program is started _automatically_ (i.e., without
human intervention) even with the "pl" capability unset, as soon
as a PPP frame is detected. But with "pl" set, a PPP login program
is started independently of the result of PPP detection (which is
rendered unnecessary then,) i.e. _unconditionally_.

General mdoc(7) markup fixes:

Improve the language and markup of the description of the pp and pl
capabilities:

- Mark up capability identifiers.
- Don't squeeze much text into the capability table given the options
will be described below in detail.
- Keep the capability table sorted.
- Use a consistent term for a PPP login program.

mdoc(7) police: expand contraction.

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)

$Id$ -> $FreeBSD$

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!)

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.

Use the .Bx macro where appropriate.

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.

Back this change out. It's just not worth arguing over and any further emails
I get on this topic will go straight to /dev/null. This is absolutely the
last word on this topic you'll see from me. Too much time has already been
wasted.

A useful aid.. Add support for:

%r: current release
%m: machine architecture type (i386 for now)
%s: OS name (FreeBSD)
