public void map_connection (string handle_name, SparqlConnection service_connection)
Maps a `TrackerSparqlConnection` onto another through a `private:handle_name` URI.
This can be accessed via the SERVICE SPARQL syntax in queries from this. E.g.:
```c tracker_sparql_connection_map_connection (connection, "other-connection", other_connection); ```
```sparql SELECT ?u { SERVICE <private:other-connection> { ?u a rdfs:Resource } } ```
This is useful to interrelate data from multiple `TrackerSparqlConnection` instances maintained by the same process, without creating a
public endpoint for service_connection.
this may only be a `TrackerSparqlConnection` created via [ctor@SparqlConnection.new] and [ func@SparqlConnection.new_async].
