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.

* Register cleanup function with atexit
instead of calling it explicitly on
exit()
* abort() no longer calls _cleanup:
Flushing stdio buffers on abort is no
longer required by POSIX.
* dlmalloc no longer need to reset cleanup
(see above)
* Upstream findfp.c makebuf.c setvbuf.cexit.c
to openbsd versions.

Use the upstream OpenBSD implementations of these functions.
Also ensure we have symbols for htonl, htons, ntohl, and ntohs.
gtest doesn't like us using the macro versions in ASSERT_EQ.

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.

Although glibc gets by with an 8-byte mbstate_t, OpenBSD uses 12 bytes (of
the 128 bytes it reserves!).
We can actually implement UTF-8 encoding/decoding with a 0-byte mbstate_t
which means we can make things work on LP32 too, as long as we accept the
limitation that the caller needs to present us with a complete sequence
before we'll process it.
Our behavior is fine when going from characters to bytes; we just
update the source wchar_t** to say how far through the input we got.
I'll come back and use the 4 bytes we do have to cope with byte sequences
split across multiple input buffers. The fact that we don't support
UTF-8 sequences longer than 4 bytes plus the fact that the first byte of
a UTF-8 sequence encodes the length means we shouldn't need the other
fields OpenBSD used (at the cost of some recomputation in cases where a
sequence is split across buffers).
This patch also makes the minimal changes necessary to setlocale(3) to
make us behave like glibc when an app requests UTF-8. (The difference
being that our "C" locale is the same as our "C.UTF-8" locale.)

This also gets us the C99 wcstoimax and wcstoumax, and a working fgetwc and
ungetwc, all of which are needed in the implementation.
This also brings several other files closer to upstream.

This replaces a partial set of non-functional functions with a complete
set of functions, all of which actually work.
This requires us to implement mbsnrtowcs and wcsnrtombs which completes
the set of what we need for libc++.
The mbsnrtowcs is basically a copy & paste of wcsnrtombs, but I'm going
to go straight to looking at using the OpenBSD UTF-8 implementation rather
than keep polishing our home-grown turd.
(This patch also opportunistically switches us over to upstream btowc,
mbrlen, and wctob, since they're all trivially expressed in terms of
other functions.)

These were defined in upstream's per-arch files, so I carried them across,
but they aren't actually used anywhere.

Adding the perfunctory <ctype.h> tests showed that we'd accidentally
dropped several symbols. This puts everything back in its proper place
and switches us to upstream head at the same time.

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

Add tests for the above.
Add the fortify implementations of __stpcpy_chk and __stpncpy_chk.
Modify the strncpy test to cover more cases and use this template for
stpncpy.
Add all of the fortify test cases.

lconv is taken from ndk/sources/android/support/include/locale.h and

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 new implementation is a better approximation to the processor time used
by the process because it's actually based on resource usage rather than just
elapsed wall clock time.

The only way the setitimer call can fail is if the unsigned number of seconds is
too large to fit in the kernel's signed number of seconds. If you schedule a
68-year alarm, glibc will fail by returning 0 and BSD will fail by returning -1.
