The goal here is to remove a slot (making way to turn make_new into a slot) as well as reduce code size by the ~40 references to mp_identity_getiter and mp_stream_unbuffered_iter. This introduces two new type flags: - MP_TYPE_FLAG_ITER_IS_ITERNEXT: This means that the "iter" slot in the type is "iternext", and should use the identity getiter. - MP_TYPE_FLAG_ITER_IS_CUSTOM: This means that the "iter" slot is a pointer to a mp_getiter_iternext_custom_t instance, which then defines both getiter and iternext. And a third flag that is the OR of both, MP_TYPE_FLAG_ITER_IS_STREAM: This means that the type should use the identity getiter, and mp_stream_unbuffered_iter as iternext. Finally, MP_TYPE_FLAG_ITER_IS_GETITER is defined as a no-op flag to give the default case where "iter" is "getiter". Signed-off-by: Jim Mussared <jim.mussared@gmail.com>
