    libtracker-data: Rename confusing TrackerDBStatement field
    
    Now that the TrackerDBStatement is a GInitiallyUnowned, the
    stmt_is_sunk boolean field is somewhat confusing. It is used
    to keep track of the stmts being currently in use by a
    TrackerDBCursor, renaming it to stmt_is_used seems more obvious.
