Provides a concrete state type that can be dynamically added. This is necessary for op crates. * renames BasicState to OpState * async ops take `Rc<RefCell<OpState>>` * sync ops take `&mut OpState` * removes `OpRegistry`, `OpRouter` traits * `get_error_class_fn` moved to OpState * ResourceTable moved to OpState
