d05090827f Back out the `hiding' of strlcpy and strlcat. Several people
vocally objected to this safety belt.

5723e501ab `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 interfering and buggy version of strlcpy

e37f8b5313 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.

68cd9bedfb Stylistic changes:
o Fix an English error (comma splice) and poorly worded sentence.
o Fix KNF ordering of variables (pointers come before arithmetic types).
o Restore hand-optimization of sizeof()-1, instead of strlen().
o Remove unneeded local variables in strerror_r().

5a98f074e6 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.

556f162ac0 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.

5ec11cf0bb Fix printing of weird errno's: negative values were printed as large
unsigned's; null termination was only guaranteed for the first call.

Fix lint: don't declare externs internally; they were both out of date.
