 1.4  01-Nov-2024  riastradh string.h: Fix various symbol visibility issues.

1. Order declarations according to POSIX 2024 to make this easier to
review side-by-side with the spec.
2. Fix visibility of memccpy: XSI-only, not POSIX in general; require
_XOPEN_SOURCE, not just _POSIX_C_SOURCE.
3. Omit redundant _XOPEN_SOURCE test around stpcpy/stpncpy.
4. Hide strdup in POSIX 2001. Not POSIX (without XSI) until 2008.
5. Hide strerror_r until POSIX 2001. Can't find evidence of it in
any earlier POSIX or X/Open. (Not 100% sure on this one, maybe
someone can double-check my research.)
6. Add restrict to strlcat/strlcpy.
7. Omit redundant _XOPEN_SOURCE test around strndup and strnlen.
8. Hide strtok_r until POSIX 2001. Can't find evidence of it in
any earlier POSIX or X/Open. (Not 100% sure on this one, maybe
someone can double-check my research.)

Carry the restrict qualifiers on strlcat/strlcpy to libkern too.
