does not support MYSQL_SECURE_AUTH option; breaks MySQL Connector/C++

MySQL Connector/C++ version 1.1.4 calls mysql_options with MYSQL_SECURE_AUTH (even if the caller of Connector/C++ did not request anything related to secure auth; Connector/C++ enforces a default of "true"). The MariaDB Client Library for C does not implement this option, returns an error code to mysql_options, which makes MySQL Connector/C++ bail out and cancel the connection.
