Correct BUGS description of static buffer use

Since r142667 strerror has unconditionally returned a pointer to a
static buffer.

Add err(3) to strerror(3) SEE ALSO section

Allow strerror(0) and strerror_r(0, ...).

Of course, strerror_r() may still fail with ERANGE.

Although the POSIX specification said this could fail with EINVAL and
doing this likely indicates invalid use of errno, most other
implementations permitted it, various POSIX testsuites require it to
work (matching the older sys_errlist array) and apparently some
applications depend on it.

Add back the Standards section claiming conformance to 1003.1-2001 and
C99 now that all known standards-related bugs have been fixed.

Rearrange strerror() so that its itoa procedure can be used with
strerror_r(). Doing this allows us to ensure that strerror_r() always
fills the supplied buffer regardless of EINVAL or ERANGE errors.

strerror()'s semantics have changed slightly such that an argument of
0 is now considered invalid and errno is set to EINVAL.

Remove internal regression test for strerror() and strerror_r(). This
will be reincarnated in src/tools/regression/lib/libc/string.

In strerror(3), add a comment about strerror()'s bogus return type.

Remove the Standards section again until we get these functions sorted
out. This will probably have to wait until after 5.0-R.

Add a Standards section, claiming conformance to IEEE Std. 1003.1-2001.
Also add a note to the Bugs section pointing out that strerror() and
perror() share the same static buffer.

Revert last commit. stdio.h include is for perror(), not strerror()

mdoc(7) police: minor markup nits.

Make strerror and strerror_r use sys_errlist[0] for errnum = 0. Be
more careful about reporting truncation with ERANGE in strerror_r.
Set errno to EINVAL for "unknown" errnum in strerror as required
by P1003.1-200x Draft June 14, 2001.

More carefully document the handling of strerrbuf when errors
(ERANGE, EINVAL) are encountered in strerror_r.

Add $Id$, to make it simpler for members of the translation teams to
track.

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.
