This only touches the easy stuff.

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.

a89864a20b Move non-upstream code into the libc/bionic directory.
I'll need at least one more pass, because there's some upstream code
lurking in libc/bionic, but this is still a step in the right direction.

91875dcd6e Fix tmpfile(3).
This could be better, but at least now it works.

c7dcd67d56 Add missing va_end() to prevent stack corruptions
Added va_end() for copied variable arguments lists
in __vfprintf() and __find_arguments().
This is by C standard.
Important for systems which pass arguments in registers.

9b549c39c9 FORTIFY_SOURCE: add sprintf / vsprintf support
sprintf FORTIFY_SOURCE protections are not available
on clang.

Also add various __attribute__s to stdio functions.

cffdf6693f FORTIFY_SOURCE: add snprintf, vsnprintf
Add _FORTIFY_SOURCE support for snprintf, vsnprintf

At this time, we opt out of these protections for clang, as clang
does not implement __builtin_va_arg_pack().

9831ad3ce6 libc: speed-up flockfile()/funlockfile()
For Honeycomb, we added proper file thread-safety for
all FILE* operations. However, we did implement that by
using an out-of-band hash table to map FILE* pointers
to phtread_mutex_t mutexes, because we couldn't change
the size of 'struct _sFILE' without breaking the ABI.

It turns out that our BSD-derived code already has
some support code to extend FILE* objects, so use it
instead. See libc/stdio/fileext.h

This patch gets rid of the hash table, and put the
mutex directly into the sFILE extension.

712e4f81e0 vfscanf: Add support for L type modifier for long long
scanf()'s man page suggests support for %Ld, (and ioux).
Implement this so that 3rd party code will work correctly.

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.

b4867734b0 stdio: make internal symbols static/hidden
Although header libc/stdio/local.h declares the macros and private
variables of stdio, there are several internal symbols exposed
unexpectedly.
