libc++ still depends on these being declared even if they are
unavailable. This results in a worse error message (a link error
rather than a compiler diagnostic) if these functions end up being
used, but without the decl headers like libc++'s math.h can't be
included because it refers to an undeclared function.
For the cases where weak symbols aren't being used, don't annotate
these functions with their availability information.
Also need to avoid using __builtin_available for this case because the
NDK doesn't have __isOSVersionAtLeast yet.
__ANDROID_UNGUARDED_AVAILABILITY__ is being used as a proxy for
"building for the NDK" here because we don't have a good signal for
that which works for both the NDK proper and the NDK-in-the-platform
case.
Test: imported into the NDK, built and tested NDK

This reverts commit 079bff4fa5.
Broke builds with SANITIZE_HOST=address with an asan failure in versioner.

libstdc++ needs to be able to `using ::foo` these in the various C++
wrapper headers for the C library. The NDK long ago added fake
definitions. We need to keep the same.

Various things:
* work around -Wnullability-completeness.
* use C++ casts in C++ and C casts in C.
* stop using attributes clang doesn't support (such as `warning`).
* remove duplicate definitions of XATTR_CREATE and XATTR_REPLACE.

The OpenBSD doesn't support C99, and the extent to which we support
locales is trivial, so just do it ourselves.

lconv is taken from ndk/sources/android/support/include/locale.h and
matches
bsd/glibc upstream.
Keep old declaration for 32-bits for compatibility.
localeconv.c and deps are taken from openbsd upstream.
Changed strtod.c accordingly.

The DNS copy of reentrant.h was unused, so remove it.
The strtod implementation can use the upstream-netbsd reentrant.h and
get a little closer to what was then upstream. (It's since been replaced
by gdtoa, and we'll have to follow at some point, but for now this doesn't
make anything any worse.)
ANDROID_CHANGES is (now) only used in the DNS code, so push the -D
down.
The <locale.h> change prevents an LP32 hack from leaking into LP64.
