[issue6873] posix_lchown: possible overflow of uid, gid

[Boya Sun]

New submission from Boya Sun <boya.sun at case.edu>:

posix_lchown(PyObject *self, PyObject *args)
{
        ...
 	int uid, gid;
        ...
 	if (!PyArg_ParseTuple(args, "etii:lchown",
 	                      Py_FileSystemDefaultEncoding, &path,
 	                      &uid, &gid))
        ...
}

uid and gid could cause over flow. A similar bug is issue 5705.

Patch attached.  Any comment is appreciated!
