+ * int plugin_init_mysql (void)
+ *
+ *  adds various functions:
+ *     MySQLquery(query) 
+ *        Returns the number of rows in query.
+ *     MySQLstatus()
+ *        Returns the current server status:
+ *        Uptime in seconds and the number of running threads,
+ *        questions, reloads, and open tables.
