9183be81a7 stdio.h: Fix function-type typedef style and use _types.h __ssize_t
I'm still not sure why only Pypy runs into the error with the function
typedefs.  Fix it anyway.

Use __ssize_t instead of ssize_t for the types; it's possible for the size_t
type to not be visible if at the wrong POSIX_VISIBLE level.

A final (crossing my fingers) follow-up to r299456.

6710d21d9f Pollute more places with off64_t and add __off64_t
Despite the private namespace, several broken ports depend on the __off64_t
name for the type.  Export it exactly the same way off_t and __off_t are
exported.

A follow-up to r299456.

9240031ac6 Add an implementation of open_memstream() and open_wmemstream(). These
routines provide write-only stdio FILE objects that store their data in a
dynamically allocated buffer.  They are a string builder interface somewhat
akin to a completely dynamic sbuf.

c17bf9a9a5 Next round of stdio changes: Remove all inlining of stdio operations and
move the definition of the type backing FILE (struct __sFILE) into an
internal header.
- Remove macros to inline certain operations from stdio.h.  Applications
  will now always call the functions instead.
- Move the various foo_unlocked() functions from unlocked.c into foo.c.
  This lets some of the inlining macros (e.g. __sfeof()) move into
  foo.c.
- Update a few comments.
- struct __sFILE can now go back to using mbstate_t, pthread_t, and
  pthread_mutex_t instead of knowing about their private, backing types.

1e98f88776 Next stage of stdio cleanup: Retire __sFILEX and merge the fields back into
__sFILE.  This was supposed to be done in 6.0.  Some notes:
- Where possible I restored the various lines to their pre-__sFILEX state.
- Retire INITEXTRA() and just initialize the wchar bits (orientation and
  mbstate) explicitly instead.  The various places that used INITEXTRA
  didn't need the locking fields or _up initialized.  (Some places needed
  _up to exist and not be off the end of a NULL or garbage pointer, but
  they didn't require it to be initialized to a specific value.)
- For now, stdio.h "knows" that pthread_t is a 'struct pthread *' to
  avoid namespace pollution of including all the pthread types in stdio.h.
  Once we remove all the inlines and make __sFILE private it can go back
  to using pthread_t, etc.
- This does not remove any of the inlines currently and does not change
  any of the public ABI of 'FILE'.

12eb46c8bb Change the definition of NULL on ia64 (for LP64 compilations) from
an int constant to a long constant. This change improves consistency
in the following two ways:
1. The first 8 arguments are always passed in registers on ia64, which
   by virtue of the generated code implicitly widens ints to longs and
   allows the use of an 32-bit integral type for 64-bit arguments.
   Subsequent arguments are passed onto the memory stack, which does
   not exhibit the same behaviour and consequently do not allow this.
   In practice this means that variadic functions taking pointers
   and given NULL (without cast) work as long as the NULL is passed
   in one of the first 8 arguments. A SIGSEGV is more likely the
   result if such would be done for stack-based arguments. This is
   due to the fact that the upper 4 bytes remain undefined.
2. All 64-bit platforms that FreeBSD supports, with the obvious
   exception of ia64, allow 32-bit integral types (specifically NULL)
   when 64-bit pointers are expected in variadic functions by way of
   how the compiler generates code. As such, code that works correctly
   (whether rightfully so or not) on any platform other than ia64, may
   fail on ia64.

To more easily allow tweaking of the definition of NULL, this commit
removes the 12 definitions in the various headers and puts it in a
new header that can be included whenever NULL is to be made visible.

This commit fixes GNOME, emacs, xemacs and a whole bunch of ports
that I don't particularly care about at this time...
