/// \brief Create an SQLite3 data source client from a zone file.
///
/// This function creates an SQLite3 client for the specified zone containing
/// RRs in the specified zone file.  The zone will be created in the given
/// SQLite3 database file.  The database file does not have to exist; this
/// function will automatically create a new file for the test; if the given
/// file already exists this function overrides the content (so basically the
/// file must be an ephemeral one only for that test case).
///
/// The zone file must be formatted so it's accepted by the dns::masterLoad()
/// function.
///
/// \param zclass The RR class of the zone
/// \param zname The origin name of the zone
/// \param db_file The SQLite3 data base file in which the zone data should be
/// installed.
/// \param zone_file The filename of the zone data in the textual format.
/// \return Newly created \c DataSourceClient using the SQLite3 data source
