Fix for crash in mySQL ODBC Driver

the MySQL ODBC Driver was not properly honoring the RETRIEVE_DATA attribute, which is used by the OLEDB Provider for ODBC Driver.

This patch resolves that problem.

under driver, the affected files & lines are

options.c - line 110:
                                    options->retrieve_data = (SQLULEN) ValuePtr;
options.c - line 184:
            *((SQLUINTEGER *) ValuePtr)= options->retrieve_data;
handle.c  -- line 210:
                                    dbc->stmt_options.retrieve_data = TRUE;

results.c - line 1547:

                        if (stmt->stmt_options.retrieve_data)
                                    res= fill_fetch_buffers(stmt, values, i);


Thanks
