mariadb/mysql-test/r/events.result
unknown cace147c63 WL#3337 (Event scheduler new architecture) Fourth cut of refactoring 
the parsing. Next step will be to refactor of usage of Event_timed 
during Events::create_event() and Events::update_event().

Disallow:
- CREATE EVENT ... DO CREATE EVENT ...;
- ALTER  EVENT ... DO CREATE EVENT ...;
- CREATE EVENT ... DO ALTER EVENT DO ....;
- CREATE PROCEDURE ... BEGIN CREATE EVENT ... END|

Allowed:
- CREATE EVENT ... DO DROP EVENT yyy;
- CREATE EVENT ... DO ALTER EVENT yyy;
  (the nested ALTER EVENT can have anything but DO clause)
- ALTER  EVENT ... DO ALTER EVENT yyy;
  (the nested ALTER EVENT can have anything but DO clause)
- ALTER  EVENT ... DO DROP EVENT yyy;
- CREATE PROCEDURE ... BEGIN ALTER EVENT ... END|
  (the nested ALTER EVENT can have anything but DO clause)
- CREATE PROCEDURE ... BEGIN DROP EVENT ... END|

mysql-test/t/events.test:
  use number as error, mysql-test-run does not like the name.
  will come back to this later, now it's enough to pass the test.
  disable nested events / events in SP, when the nested event has
  a body. If no body is provided, namely DROP EVENT or ALTER that
  changes the characteristics, then these are allowed.

sql/share/errmsg.txt:
  new message
sql/sql_yacc.yy:
  refactor CREATE EVENT parsing to fit into the structure
  CREATE DEFINER=xxx EVENT
  The actual definer part is not used, but parsed, for now.
  Disable nested CREATE EVENTS, CREATE EVENT inside CREATE PROCEDURE.
  And an event DDL with body inside an ALTER.
  This stops the following :
  - CREATE EVENT ... DO CREATE EVENT ...;
  - ALTER  EVENT ... DO CREATE EVENT ...;
  - CREATE EVENT ... DO ALTER EVENT DO ....;
  - CREATE PROCEDURE ... BEGIN CREATE EVENT ... END|
  This allows:
  - CREATE EVENT ... DO DROP EVENT yyy;
  - CREATE EVENT ... DO ALTER EVENT yyy;
    (the nested ALTER EVENT can have anything but DO clause)
  - ALTER  EVENT ... DO ALTER EVENT yyy;
    (the nested ALTER EVENT can have anything but DO clause)
  - ALTER  EVENT ... DO DROP EVENT yyy;
  - CREATE PROCEDURE ... BEGIN ALTER EVENT ... END|
    (the nested ALTER EVENT can have anything but DO clause)
  - CREATE PROCEDURE ... BEGIN DROP EVENT ... END|
