e2341d08fa Disable %n in printf and vfwprintf.

01ae00f317 Switch to the OpenBSD implementations of the wide scanf functions.
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.

0549371bd7 Upgrade to current vfprintf.
This gets us various bug fixes and missing C99 functionality.

f2cea021ab Clean up <stdio.h> macros.
Also neuter __isthreaded.

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

1d13c64d78 Fix %hhd formats in the printf family.
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.

61e699a133 Clean up abort.
* 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.

f27b7fb056 Define DEFFILEMODE and friends
Define the macros ACCESSPERMS, ALLPERMS and DEFFILEMODE.
These macros originates from BSD but has been available in glibc
for quite some time.

f582340a6a Fix the handle locking in stdio
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.
