Remove the done and error callbacks. The error callback is in an error message. The done callback is replace with spa_pending. Make enum_params take a callback and data for the results. This allows us to push the results one after another to the app and avoids ownership issues of the passed data. We can then extend this to handle the async case by doing a _wait call with a spa_pending+callback+data that will be called when the _enum_params returns and async result. Add a sync method. All methods can now return SPA_RESULT_IS_ASYNC return values and you can use spa_node_wait() to register a callback when they complete with optional extra parameters. This makes it easier to sync and handle the reply. Make helper methods to simulate the sync enum_params behaviour for sync nodes. Let the transport generate the sequence number for pw_resource_sync() and pw_proxy_sync(). That way we don't need to keep track of numbers ourselves and we can match the reply to the request easily.
