MFC r241848:
Check the return error of set[e][ug]id. While this can never fail in the
current version of FreeBSD, this isn't guarenteed by the API.
Custom security modules, or future implementations of the setuid and
setgid may fail.

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

If one's message is longer than the buffer size, then we reset 'cnt' at the
wrong point and the actual column # get out of sync across the buffer size.

Remove the advertising clause from UCB copyrighted files in usr.bin. This
is in accordance with the information provided at
ftp://ftp.cs.berkeley.edu/pub/4bsd/README.Impt.License.Change

Also add $FreeBSD$ to a few files to keep svn happy.

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.

Add missing `void' keyword.

Let wall(1) use utmpx.

Because our implementation guarantees the strings inside struct utmpx to
be null terminated, we don't need to copy everything out, which makes
the code nicer to read.

Also set WARNS to 6 and add $FreeBSD$ to keep SVN silent.

Fix some bugs in wall(1):
- Handle wrapping correctly when \r appears in the input, and don't
remove the \r from the output.
- For lines longer than 79 characters, don't drop every 80th character.
- Style: Braces around compound while statement.

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.

Remove "sleeper" nonsense.

WARNS=2 fix, use __FBSDID().

Not added to Makefile as WARNS=2 will be made default.

- Move the prototype of ttymsg() into ttymsg.h. syslogd and talkd
also use this, and they shouldn't have to have their own prototypes.

- Silence warnings about constness and signedness in ttymsg(). This
includes changing the return value to a `const char *', and changing
the types of `left' and `wret' (both byte counts) to ssize_t.

Cleanup this code a bit by attempting to sync it up with NetBSD and

Instead of printing '(null)' if there is no tty, print 'no tty'.

In the case where the program is executed by a daemon running in the
background the terminal might not have a tty. The '(null)' is confusing.

Let wall report the local timezone as well on output.
