Here we define the descriptor structure, that is referred from
st_mysql_plugin.
release_thd() event occurs when the event class consumer is to be
disassociated from the specified THD. This would typically occur
before some operation which may require sleeping - such as when
waiting for the next query from the client.
event_notify() is invoked whenever an event occurs which is of any
class for which the plugin has interest. The first word of the
mysql_event argument indicates the specific event class and the
remainder of the structure is as required for that class.
class_mask is an array of bits used to indicate what event classes
that this plugin wants to receive.
