Style: put static qualifier on definition of static functions.

Respect the setting of the COLUMNS environment variable, use it instead of
the TTY width obtained by ioctl() when set & non-null. (SUSv3)

Write "FROM" heading above the hostname column, like NetBSD and GNU do.

Reimplement the who(1) utility to add some features required by SUSv3:
-H option (show column headings),
-T (show mesg(1) state),
-m (same as "am I"),
-u (show idle time),
-q (quick mode; list names

remove __P

WARNS=2 fix, use __FBSDID().

WARNS=2 is not in Makefile, as this will be the default.

Include missing header files which define functions for which gcc has
builtins (e.g., exit, strcmp).

Don't attempt to parse %c

$Id$ -> $FreeBSD$

Back out Steve's fix, as this was already fixed by me in revision 1.6

Only allow 'who' and 'who am i' as valid usages.

Check that user really typed "who am {I,i}", and that no stray
arguments are given.

Use err(3). Add usage().

Made sure the string formated by strftime() is properly
null-terminated.

Fixed a wrong if statement which should test a string is
empty where in fact it tested the string pointer was NULL.

BSD 4.4 Lite Usr.bin Sources

Perform all trivial ports to utmpx for usr.bin/.

They were already converted to use libulog, so it's easy to convert them
to utmpx.

Merge from head at r201628.

# This hasn't been tested, and there are at least three bad commits
# that need to be backed out before the branch will be stable again.

Several refinements to libulog's API.

- Only set the fields in the ulog_utmpx structure that are valid for the
command in question. This means that strings like "shutdown" or "~"
are not visible

Several refinements to libulog's API.

- Only set the fields in the ulog_utmpx structure that are valid for the
command in question. This means that strings like "shutdown" or "~"
are not visible to the user anymore.
- Rename UTXF_* to UTXI_*, indicating the indexation, instead of using
the `antique' filename. If we ever get rid of utmp, it makes little
sense calling it by its old name.

Revert most part of 200420 as requested, as more review and polish is

Remove unneeded header includes from usr.bin/ except contributed code.

Port who(1) to utmpx.

(Un)fortunately there is no standardized interface to switch between
utmp database files, so we must call ulog_setutxfile() here.

I'm also changing the column widths to magic

Port who(1) to utmpx.

(Un)fortunately there is no standardized interface to switch between
utmp database files, so we must call ulog_setutxfile() here.

I'm also changing the column widths to magic numbers here. Display
layout should in this case not be derived from structure fields sizes.
Because I don't want struct utmpx ever to become too small, the fields
are too big to reserve all the space.

In wall and who, check that the utmp entry isn't stalled, as it is done in w.
Apparently with the new pts code stalled entries are printed, when they are
not with the BSD ptys.
