50e04779c4 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.

wrong point and the actual column # get out of sync across the buffer size.

da52b4caaf 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.

ab90a4d1e2 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.

bd76376f80 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.

3c58f6ddbd 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.

b457a3e19c 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.

728d043e5b - 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.

80af0816cd 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.

Increase the size of a number of buffers and replace strcpy/strcat/sprintf
    with snprintf().  There was a minor and possibly not exploitable security
    hole related to one sprintf().
