Make struct spa_node_events for events emited from the main thread and keep the spa_node_callbacks for the data thread callbacks. The add_listener method installs the events and it's possible to install multiple handles. Adding a listener first emits the info and port_info events when installed, similar to how the PipeWire proxy bind works. This removes the need for the spa_pending_queue and makes it easier to implement the _sync versions. Add some helpers to make it easier for plugins to emit all the info to new listeners. Use the listeners for devices as well.
