e.g.MYSQL_AUDIT_GENERAL_ERROR General audit API (MYSQL_AUDIT_GENERAL_CLASS) didn't expose event subclass to plugins. This patch exposes event subclass to plugins via struct mysql_event_general::event_subclass. This change is not compatible with existing general audit plugins. Audit interface major version has been incremented. include/mysql/plugin_audit.h: Expose event subclass to audit general plugins. plugin/audit_null/audit_null.c: Added distinct counters for general event sub-classes. Removed printf() from deinit(). One can easily see number of calls via status variables. To make code nicer, modified class mask to use macro instead of hardcoded number. Incremented audit plugin minor version. sql/sql_audit.cc: Expose event subclass to audit general plugins.
