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.

Make it visible under XOPEN_SOURCE>=700 too (not just _NETBSD_SOURCE).

consttime_memequal is the same as the old consttime_bcmp.
explicit_memset is to memset as explicit_bzero was to bcmp.

so please let me know.

Add "consttime_bcmp" and "explicit_bzero" functions for both kernel
abd userland, as proposed on tech-security, with explicit_bzero using
a volatile function pointer as suggested by Alan Barrett.
Both do what the name says. For userland, both are prefixed by "__"
to keep them out of the user namespace.
Change some memset/memcmp uses to the new functions where it makes
sense -- these are just some examples, more to come.

(mips, alpha) or it's known broken (sh3). But enable FORTIFY_SOURCE,
without SSP, on those platforms -- tested on mipsel.

bjh21 | Add a new feature-test macro, _NETBSD_SOURCE. If this is defined
by the application, all NetBSD interfaces are made visible, even
if some other feature-test macro (like _POSIX_C_SOURCE) is defined.
<sys/featuretest.h> defined _NETBSD_SOURCE if none of _ANSI_SOURCE,
_POSIX_C_SOURCE and _XOPEN_SOURCE is defined, so as to preserve
existing behaviour.
This has two major advantages:
+ Programs that require non-POSIX facilities but define _POSIX_C_SOURCE
can trivially be overruled by putting -D_NETBSD_SOURCE in their CFLAGS.
+ It makes most of the #ifs simpler, in that they're all now ORs of the
various macros, rather than having checks for (!defined(_ANSI_SOURCE) ||
!defined(_POSIX_C_SOURCE) || !defined(_XOPEN_SOURCE)) all over the place.
I've tried not to change the semantics of the headers in any case where
_NETBSD_SOURCE wasn't defined, but there were some places where the
current semantics were clearly mad, and retaining them was harder than
correcting them. In particular, I've mostly normalised things so that
_ANSI_SOURCE gets you the smallest set of stuff, then _POSIX_C_SOURCE,
_XOPEN_SOURCE and _NETBSD_SOURCE in that order.
Tested by building for vax, encouraged by thorpej, and uncontested in
tech-userlevel for a week.

kleink | For the benefit of G++'s null pointer constant implementation, #define NULL
as __null with egcs 1.0 (GCC 2.90) and above. As several headers are affected
by this change, move the definition into a new header file, <null.h>, to ease
maintenance.
