* libc/include/sys/reent.h: Add _GLOBAL_REENT macro.
* libc/stdio: Globally remove/replace all references to fp->_data.
Replace with _REENT or _GLOBAL_REENT where appropriate.
* libc/stdio/asprintf.c: Ditto.
* libc/stdio/fclose.c: Ditto.
* libc/stdio/fvwrite.c: Ditto.
* libc/stdio/makebuf.c: Ditto.
* libc/stdio/refill.c: Ditto.
* libc/stdio/local.h: Ditto.
* libc/stdio/setvbuf.c: Ditto.

* libc/stdio/stdio.c: Ditto.
* libc/stdio/ungetc.c: Ditto.
* libc/stdio/vfscanf.c: Ditto.
* libc/stdio/vsscanf.c: Ditto.
* libc/stdio/fopen.c: Ditto. Also use _fseek_r in _fopen_r.
* libc/stdio/vasprintf.c: Ditto. Also call _vfprintf_r directly.
* 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/printf.c: Ditto.
* libc/stdio/snprintf.c: Call _vfprintf_r directly.
* libc/stdio/sprintf.c: Ditto.
* libc/stdio/vprintf.c: Ditto. Also add _REENT_ONLY check.
* 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.
