[tracker/dbus-fd-experiment-squashed: 3/6] Add Steroids example client

[Adrien Bustany <abustany src gnome org>]

commit 505976793ddd5b2adc54d215b6de1cc047b73478

    Add Steroids example client
    
    This commit adds a steroids-sparql program. This program shows how to
    use the tracker_resources_sparql_query_iterate function to do a query
    and fetch the results. It does exactly the same thing as
    tracker-sparql -q. This commit also adds an async version.
