* libc/include/stdio.h[!_REENT_ONLY]: Moved various functions together
into one list.
[!__STRICT_ANSI__]: Moved non-ANSI I/O functions in this list.
(vfscanf, vscanf, vsscanf, _vfscanf_r, _vscanf_r, _vsscanf_r): New
function prototypes.
(_fscanf_r, _sscanf_r): Ditto.
* libc/include/stdlib.h: Added _strtod_r prototype.
* libc/stdio/Makefile.am: Add new v*scanf functions.
* libc/stdio/Makefile.in: Regenerate.
* libc/stdio/fscanf.c: Reorganized so HAVE_STDC only affects prototype
and code is shared. Added reentrant _fscanf_r which calls __svfscanf_r. * libc/stdio/scanf.c: Changed to call __svfscanf_r.
* libc/stdio/sscanf.c: Changed documentation to add reentrant routines.
(sscanf): Changed to call __svfscanf_r with _REENT argument.
(_sscanf_r): New routine.
* libc/stdio/local.h: Removed __svfscanf prototype and replaced it
with __svfscanf_r prototype.
* libc/stdio/vfscanf.c (vfscanf, _vfscanf_r: New
routines.
(__svfscanf_r): Reentrant version of __svfscanf which takes reetrancy
structure as argument as calls reentrant versions of helper functions
(e.g. _strtol_r, _strtoul_r). Also replaced calls to atol and atof
to _strtol_r and _strtod_r respectively.
* libc/stdio/vfscanf.c: Also changed __svfscanf to call __svfscanf_r.
* libc/stdlib/strtod.c (strtod): Changed to call _strtod_r with
_REENT argument.
* libc/stdio/vscanf.c: New file.
* libc/stdio/vsscanf.c: Ditto.
