	* libc/stdio/vsnprintf.c: Ditto.
	* libc/stdio/vsprintf.c: Ditto.
	* libc/stdio/fcloseall.c(fcloseall): Use _GLOBAL_REENT macro
	instead of _REENT to walk file list.
	* libc/stdio/fflush.c: Ditto.
	* libc/stdio/fgetpos.c: Add reentrant version and have regular
	version call reentrant version with _REENT argument.
	* libc/stdio/fsetpos.c: Ditto.
	* libc/stdio/fseek.c: Ditto.
	* libc/stdio/fseeko.c: Ditto.
	* libc/stdio/ftell.c: Ditto.
	* libc/stdio/ftello.c: Ditto.
	* libc/stdio/freopen.c: Ditto.
	* libc/stdio/findfp.c: Use _GLOBAL_REENT pointer when adding
	new files to chain.  Also use _GLOBAL_REENT pointer for
	cleaning up.
	* libc/stdio/fiprintf.c: Reformatted to minimize duplicate code.
	* libc/stdio/siprintf.c: Ditto.
	* libc/stdio/iprintf.c: Ditto.
	* libc/stdio/fprintf.c: Ditto.

	* libc/stdio/rewind.c: Call _fseek_r directly.
	* libc/stdio/tmpfile.c: Call _fopen_r and _remove_r directly.
	* libc/stdio/vfprintf.c (_VFPRINTF_R): Change _r routines to use
	data pointer.
	(get_arg): Add extra struct _reent pointer argument.
	* libc/stdio64/fgetpos64.c: Add _r versions, remove any reference
	to fp->_data.
	* libc/stdio64/fopen64.c: Ditto.
	* libc/stdio64/freopen64.c: Ditto.
	* libc/stdio64/fsetpos64.c: Ditto.
	* libc/stdio64/ftello64.c: Ditto.
	* libc/stdio64/local64.h: Ditto.
	* libc/stdio64/stdio64.c: Ditto.
	* libc/stdio64/fseeko64.c: Ditto plus use _fstat_r instead of
	_fstat64_r for the meantime.
