41ef902379 Fix memchr overflow.
The overflow's actually in the generic C implementation of memchr.

While I'm here, let's switch our generic memrchr to the OpenBSD version too.

e6099098a5 Fix mips build.
Move various mips-only things into the arch-mips directory. As soon as mips
writes assembler replacements, we can remove these.

76f8916b90 Clean up <stdlib.h> slightly.
Interestingly, this mostly involves cleaning up our implementation of
various <string.h> functions.

8885dcc779 Add TEMP_FAILURE_RETRY to stdio's low-level read/write functions.
This is correctness rather than performance, but found while investigating
performance.

5a69da8d7a Switch to OpenBSD fopen/fclose.
This means all our stdio implementation is now the OpenBSD implementation.
The only thing we lose is the STDIO_THREAD_LOCK calls but they were no-ops
anyway.

We should probably talk to upstream about this. Either fix the locking or,
preferably, encourage them to move away from this pooling (especially since
there's no eviction policy).

b6b5cb5389 Ignore all __weak_alias in OpenBSD libC.
GCC assembler allows xyz to be redeclared as weak,
by __weak_alias(xyz, _xyz), while _xyz is undefined.
Clang does not like that but silently generates no code.
It will reject its own .s file if the assembly code is saved first.
Since we have no reason to define xyz or _xyz as weak symbol now,
and _xyz is a macro to xyz, we simplify libC to have only
xyz defined as global.

3e424d0a24 Implement twalk(3), add unit tests.
I've also added insque(3) and remque(3) (from NetBSD because the OpenBSD
ones are currently broken for non-circular lists).

I've not added the three hash table functions that should be in this header
because they operate on a single global hash table and thus aren't likely
to be useful.

6593597931 Switch to upstream OpenBSD mktemp.c.
Almost all of our stdio is actually OpenBSD, so although this isn't
really a core part of stdio (it doesn't touch struct FILE, for example)
it probably makes sense for it to come from the same upstream. My
actual motivation though is that it's the only FreeBSD file we have
compiler warnings from.

This patch moves us over to -Werror by default, with only the DNS code
having -Wno-error.

This is actually revision 1.33, which is no longer the latest, but it's
as close to head as we can currently reasonably get. I've also switched
to the OpenBSD getentropy_linux.c implementation of getentropy, lightly
modified to try to report an error on failure.

9a5a3e8e74 Fix <math.h> to quieten most of our warnings.
I've reported the wcsftime bug upstream, but we really just want to use -D
to ensure the buggy code isn't built. (I've also brought our strftime a bit
closer to upstream now we have the right define.)

I don't think upstream is likely to fix all their sign-compare and
uninitialized warnings, so let's just silence them.

As for libm, again upstream isn't likely to fix all their warnings, and
silencing those made the ones that were our fault stand out. I've fixed
our <math.h> to fix the warnings caused by our lack of definitions for
the non-imprecise long-double functions. I checked the C99 standard, and
all these functions are there.
