several fixes for mariadb_stmt_execute_direct:

Browse Source 
- allow param binding via mysql_stmt_attr_set:
  mysql_stmt_attr_set(stmt, STMT_ATTR_PREBIND_PARAMS, &param_count);
- If a prepared statement will be reexecuted, we send COM_STMT_CLOSE
  together with COM_STMT_PREPARE and COM_STMT_EXECUTE
