Port comsat to utmpx.

It seems comsat stats the utmpx database each 15 seconds to see whether
it has been changed. I am changing this behaviour to look at the utmpx
database upon processing. I don't want to allow direct interference with
the database files. I also wonder whether this optimization has any
measurable performance benefit nowadays.

Fix several warnings.

- Add __unused keywords.
- Don't shadow a global variable called cr.
- Make the global cr variable const.

Fix handling of pts(4) device names in comsat(8). Also catch fork() errors.

Pseudo-terminals allocated with posix_openpt(2) will have more slashes
in their path names than comsat(8) allows, so allow slashes when the
character device name starts with "pts/".

This patch is loosely based on NetBSD's changes, revision 1.33. Because
it also included the changes to fork(), I imported them here as well.
Maybe we could import even more fixes from the other BSD's?

Original commit message from the NetBSD folks:

PR/30170: Markus W Kilbinger: src/libexec/comsat complains
about: '/' in "/dev/pts/1"

Reported by: Robert Huff <roberthuff rcn com>

Fix most cases where the address of an int is passed to a function expecting a
socklen_t * argument.

Add ability to only beep when mail arrives.

comsat:

o Eliminate __P
o Use new-style function definitions
o remove some !__STDC__ code
o eliminate register

File positions are off_t nowdays, not long, so:
atoi -> strtoll
fseek -> fseeko

NOTE: that fseek not works for >long offsets per POSIX:

[EOVERFLOW] For fseek( ), the resulting file offset would be a value which
cannot be represented correctly in an object of type long.

Fix minor cast too.

$Id$ -> $FreeBSD$

Fixed printf format errors.

Use err(3). exit(-1) -> exit(1).

Allow backspace too

disable upper controls and enable all other
8bit codes due to lack of locale knowledge in daemon

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.

add forgotten $Id$

wrong C bracketing, *blush*...

Another sgtty use bites the dust..

Pass in both username and file to jkfprintf

Extend message format to user@offset[:file]
