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.

Unbreak !NLS case

Add NLS catalogs support to strerror(), strerror_r() and strsignal().
Controlled by NLS define, currently disabled by default.

Idea obtained from: NetBSD

Back out the `hiding' of strlcpy and strlcat. Several people
vocally objected to this safety belt.

`Hide' strlcpy and strlcat (using the namespace.h / __weak_reference
technique) so that we don't wind up calling into an application's
version if the application defines them.

Inspired by: qpopper's

Optimize errstr() by reducing the number of times it walks a string.
As a side effect, it makes the code easier to read and requires less
pointer arithmetic.

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

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.

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.
