Different meaning of flags for lock(1) and vidcontrol(1) confuse me.

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.

902d9eafbf Rework all non-contributed files that use `struct timezone'.
This structure is not part of POSIX. According to POSIX, gettimeofday()
has the following prototype:

	int gettimeofday(struct timeval *restrict tp, void *restrict tzp);

Also, POSIX states that gettimeofday() shall return 0 (as long as tzp is
not used). Remove dead error handling code. Also use NULL for a
nul-pointer instead of integer 0.

While there, change all pieces of code that only use tv_sec to use
time(3), as this provides less overhead.

2d491fabff Slightly improve output of lock(1).
- Remove the /dev/ portion of the TTY name.
- In case we use lock -p, print the username that was used to obtain the
  password hash.

54ca359425 Two fixes here:
1. If fgets fails, don't go into an infinite cpu-intensive loop.  Instead,
check to see if the terminal still exists, and sleep(1) otherwise.
2. When we check to see if the terminal still exists, make sure we're not
mislead by EINTR.  This could have been a security issue, but fortunately
the current implementation of tcgetattr doesn't EINTR.

d80646a4a0 Fix indentation: Don't use space where tabs will do; specifically,
don't use spaces at the beginning of a line where tabs are normally
used (the worst thing was that half of this file was right (tabs) and
half was wrong (spaces), making for painful reading).

cda2a9b2f0 Set BINOWN=root explicitly for setuid root binaries.
This is not "useless", as one may have non-default
setting for BINOWN in make.conf, and we still want
these to be installed setuid root in this case.

6e2578e4c4 Revert the libcrypt/libmd stuff back to how it was. This should not have
happened as it was working around problems elsewhere (ie: binutils/ld
not doing the right thing according to the ELF design).  libcrypt has
been adjusted to not need the runtime -lmd.  It's still not quite right
(ld is supposed to work damnit) but at least it doesn't impact all the
users of libcrypt in Marcel's cross-build model.

The $Id$ line is normally at the bottom of the main comment block in the
man page, separated from the rest of the manpage by an empty comment,
like so;

     .\"    $Id$
     .\"

If the immediately preceding comment is a @(#) format ID marker than the
the $Id$ will line up underneath it with no intervening blank lines.
Otherwise, an additional blank line is inserted.

2280509ca1 Closes PR bin/1567
/usr/bin/lock can be used to lock a terminal much like xlock does
for your X-windows session.  Problem is, /usr/bin/lock cannot lock
your terminal indefinately.  Rather you must specify a timeout
value, after which, your terminal is unlocked and become unsecured.

I have added a ``-n'' no timeout option to /usr/bin/lock
Currently the only way to get this functionality is to use a huge
timeout value and hope it is long enought (in time).  This method
also requires you to know the maxium number of minutes you are
allowed to specify.
