BUG#26429: SHOW CREATE EVENT is incorrect for an event that
           STARTS NOW()
BUG#26431: Impossible to re-create an event from backup if its
           STARTS clause is in the past
WL#3698: Events: execution in local time zone

The problem was that local times specified by the user in AT, STARTS
and ENDS of CREATE EVENT/ALTER EVENT statement were converted to UTC,
and the original time zone was forgotten.  This way, event scheduler
couldn't honor Daylight Saving Time shifts, and times shown to the
user were also in UTC.  Additionally, CREATE EVENT didn't allow times
in the past, thus preventing straightforward event restoration from
old backups.

This patch reworks event scheduler time computations, performing them
in the time zone associated with the event.  Also it allows times to
be in the past.

The patch adds time_zone column to mysql.event table.

NOTE: The patch is almost final, but the bug#9953 should be pushed
first.

UPDATE if the row wasn't actually changed.

This bug was caused by fix for bug#19978. It causes AFTER UPDATE triggers
not firing if a row wasn't actually changed by the update part of the
INSERT .. ON DUPLICATE KEY UPDATE.

Now triggers are always fired if a row is touched by the INSERT ... ON
DUPLICATE KEY UPDATE.

- Crash occured because Event engine is only initialized if
  ACLs are used but not properly marked as disabled.
- The patch is to mark the Event engine as DISABLED if no ACLs
  are used to avoid access of uninitialized variables.

 INSERT uses query_id to verify what fields are
 mentioned in the fields list of the INSERT command.
 However the check for that is made after the 
 ON DUPLICATE KEY is processed. This causes all
 the fields mentioned in ON DUPLICATE KEY to be 
 considered as mentioned in the fields list of 
 INSERT.
 Moved the check up, right after processing the
 fields list.
