PATCH: attr: various minor issues

The flags parameter is always 0 so the precedence mistake doesn't
actually matter.

Attributes are quite unlikely to be over 2GB in length, but use the
correct types.

The module is load=no so the autofeatures isn't used, but be consistent
and list all builtins in the mdd file.
