Fix for MDEV-12965 and MDEV-13100:

If no configuration file and no configuration group was specified, Connector/C ddoesn't read any configurationm files. By default the follwing groups will be read: - client - client-server - client-mariadb If no configuration file was specified, Connector/C looks up for configuration files in following locations: - Windows: - System directory - Windows directory - C:\ - Directoy from which the application was started - MYSQL_HOME environment variable - Unix platforms - DEFAULT_SYSCONFIR (if specified) or - /etc and /etc/mysql - MYSQL_HOME environment variable - .my.cnf in home directory Special case: If NULL or empty string will be passed for MYSQL_READ_DEFAULT_GROUP option Connector/C will read the default groups and the group which matches the application name.
