New stdio core. Should be more maintainable. Fixes a couple of bugs.
Codepaths streamlined. Improved performance for nonthreaded apps when linked with a thread-enabled libc. Minor iconv bug and some locale/thread related startup issues fixed. These showed up in getting a gcj-compiled java helloworld app running. Removed some old extension functions... _stdio_fdout and _stdio_fsfopen.

+/* April 1, 2002
+ * Initialize thread locks for fake files in vsnprintf and vdprintf.
+ * reported by Erik Andersen (andersen@codepoet.com)
+ * Fix an arg promotion handling bug in _do_one_spec for %c.
+ * reported by Ilguiz Latypov <ilatypov@superbt.com>
+ *
+ * May 10, 2002
+ * Remove __isdigit and use new ctype.h version.
+ * Add conditional setting of QUAL_CHARS for size_t and ptrdiff_t.
+ *
+ * Aug 16, 2002
+ * Fix two problems that showed up with the python 2.2.1 tests; one
+ * involving %o and one involving %f.
+ *
+ * Oct 28, 2002
+ * Fix a problem in vasprintf (reported by vodz a while back) when built
+ * without custom stream support. In that case, it is necessary to do
+ * a va_copy.
+ * Make sure each va_copy has a matching va_end, as required by C99.
+ *
+ * Nov 4, 2002
+ * Add locale-specific grouping support for integer decimal conversion.
+ * Add locale-specific decimal point support for floating point conversion.
+ * Note: grouping will have to wait for _dtostr() rewrite.
+ * Add printf wchar support for %lc (%C) and %ls (%S).
+ * Require printf format strings to be valid multibyte strings beginning and
+ * ending in their initial shift state, as per the stds.
+ *
+ * Nov 21, 2002
+ * Add *wprintf functions. Currently they don't support floating point
+ * conversions. That will wait until the rewrite of _dtostr.
+ *
+ * Aug 1, 2003
+ * Optional hexadecimal float notation support for %a/%A.
+ * Floating point output now works for *wprintf.
+ * Support for glibc locale-specific digit grouping for floats.
+ * Misc bug fixes.
+ *
+ * Aug 31, 2003
+ * Fix precision bug for %g conversion specifier when using %f style.
+ *
+ * Sep 5, 2003
+ * Implement *s*scanf for the non-buffered stdio case with old_vfprintf.
+ *
+ * Sep 23, 2003
+ * vfprintf was not always checking for narrow stream orientation.
+ */
