This patch add support of system triggers fired on server start up and shutdown. On start up triggers can be associated only with AFTER event time, on shutdown triggers associated with BEFORE event time. Several triggers can be created to be run on the same time/event type. Core implementation - Extended the sql grammar to support creation of system triggers on startup/shutdown - System triggers metadata is stored in the table mysql.event - Events and system triggers share the same name space since both are stored in the table mysql.event declared with the PRIMARY KEY (`db`,`name`). In result, attempt to create an event with the same name as existent trigger and vice versa results in failure with the new error ER_TRG_EVENT_CONFLICTS_NAME - Since system triggers metadata is stored in the mysql.event table, the table mysql.event is now opened on handling the DROP TRIGGER statement - In case server is started against old version of mysql.event table that missing columns required for support of system triggers, system trigger feature is disabled - System triggers are loaded from the table mysql.event right before their execution - System triggers can be created only by users with the SUPER privilege - Added the option --sys_triggers for mysqldump to dump system triggers. The option is turned off by default. In case this option is on, mysqldump first dump the table 'mysql' unconditionally, regardless whether it was listed in the option --ignore-database
