Originally a BSD extension, now in glibc too. We've used it internally
for a while.

This is the FreeBSD implementation, plus some tests. The FreeBSD
implementation includes the GNU extensions and seems to be what
iOS is using too, which should provide bug compatibility for app
developers.
The code unfortunately uses a lot of stack, and uses FreeBSD locale
implementation that we don't have, but it does seem better maintained
than the other BSDs.

I'm unable to find a bug, but we've had requests for this internally
once or twice (though I pointed those folks at the STL), and there's
code we build for the host or in our bootloaders that would use this,
and there's reasonable-looking FreeBSD implementation ready and waiting.

Since realpath no longer needs to be overloaded, we can restore the
upstream source to purity. We'll be able to do this with most of the
other functions when we pull a newer clang in.

Almost all of our w* functions come from FreeBSD already. The one downside is
that we can't take all our w* functions from FreeBSD because FreeBSD handles
locales very differently from us.

r279663: enhance to handle 32-bit aligned data on 64-bit systems
r279666: qsort(3): small style(9) cleanups.
r288030: Use ANSI C prototypes. Eliminates -Wold-style-definition
warnings.
r318514: Use size_t.
r318515: Reduce the possible recursion level to log2(N) by always
recursing on the smaller partition instead.

This patch adds clang-style FORTIFY to Bionic. For more information on
FORTIFY, please see https://goo.gl/8HS2dW . This implementation works
for versions of clang that don't support diagnose_if, so please see the
"without diagnose_if" sections. We plan to swap to a diagnose_if-based
FORTIFY later this year (since it doesn't really add any features; it
just simplifies the implementation a lot, and it gives us much prettier
diagnostics)

Test: Builds on angler, bullhead, marlin, sailfish. Bionic CTS tests
pass on Angler and Bullhead.

Interestingly, this mostly involves cleaning up our implementation of
various <string.h> functions.

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).

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.

* 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.

Also neuter __isthreaded.
We should come back to try to hide struct FILE's internals for LP64.

Also undo some of the mess where we have OpenBSD <stdio.h> but a mix of
different BSD's implementations.
In this first pass, I've only moved easy OpenBSD stuff.

Also fix the signature of usleep, and the definition of useconds_t which
should be unsigned, as the 'u' in its name implies.
This patch also cleans up the existing FreeBSD hacks by moving the libm
stuff from <sys/cdefs.h> to a libm-private header, and adding comments
about the hacks we use to build FreeBSD source.

Yet another archaic relic containing bugs that had been fixed years before the
Android project even started...

Fix license clause numbering.
Convert libc/stdio from K&R to ANSI C.
And add '__restrict' where it appeared in the header prototypes.

This is actually a slightly newer upstream version than the one I
originally pulled. Hopefully now it's in upstream-freebsd it will
be easier to track upstream, though I still need to sit down and
write the necessary scripts at some point.
