interfaces: improve remote API
Add return values to events and method callbacks. This makes it possible to pass any error or async return value. Add sync/done/error in both directions so that both proxy and resource and perform/reply sync and produce errors. Return a SPA_ASYNC from remote method calls (and events), keep the sequence number in the connection. With the core sync/done we can remove the client-node done method and it's internal sequence number along with the seq number in method calls. We can also use the method/event async return value to perform a sync with as the unique sequence number for this method. Add sync method and done/error event to proxy and resource.
