The LP64 has a duplicate copy of part of stdio, and relies
on bionic supplying this part. We should remove the hack from
the NDK, at least for LP64, and then revert this.

The NDK apparently includes an android_support.a library that
refers to __srefill in its copy of the vsnprintf implementation.

Anthony King <anthonydking@slimroms.net> reports that for Grouper the
Nvidia GL blobs need access to __swbuf. This is because the old <stdio.h>
had inline getc and putc implementations that directly referred to these
symbols.

I've left __sF exposed since that's how the OpenBSD stdin, stdout, stderr
are implemented. Other BSDs and glibc use a separate global for each instead
of an array.

I cleaned up most of our warnings last week but forgot to turn on -Werror,
so of course we're getting new warnings already. I've left -Werror commented
out in those places where we still have warnings to deal with before we can
turn on -Werror.

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.

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

Found by adapting the simple unit tests for libc logging to test
snprintf too. Fix taken from upstream OpenBSD without updating
the rest of stdio.

* A dlmalloc usage error shouldn't call abort(3) because we want to
cause a SIGSEGV by writing the address dlmalloc didn't like to an
address the kernel won't like, so that debuggerd will dump the
memory around the address that upset dlmalloc.
* Switch to the simpler FreeBSD/NetBSD style of registering stdio
cleanup. Hopefully this will let us simplify more of the stdio
implementation.
* Clear the stdio cleanup handler before we abort because of a dlmalloc
corruption error. This fixes the reported bug, where we'd hang inside
dlmalloc because the stdio cleanup reentered dlmalloc.

Define the macros ACCESSPERMS, ALLPERMS and DEFFILEMODE.
These macros originates from BSD but has been available in glibc
for quite some time.

Fix the handle locking in stdio to use flockfile/funlockfile
internally when and where required. Macros in <stdio.h> are updated
to automatically call the underlying functions when the process is
threaded to obtain the necessary locking. A private mutex is added
to protect __sglue, the internal list of FILE handles, and another
to protect the one-time initialization. Some routines in libc that
use getc() change to use getc_unlocked() as they're either protected
by their own lock or aren't thread-safe routines anyway.
