Simplify audioDB::query_loop_points.

Using the new functions audiodb_track_id_datum() and
audiodb_datum_qpointers(), much of the body of the method disappears.
Of course, we've probably introduced some inefficiencies and extra
memory copies, but I'm fairly sure that this method is going to be
dominated by disk i/o time anyway, so it doesn't matter.
