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|

  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|

Third cut to simplify parsing phase. Now DROP EVENT works.

Overloaded few functions to be able to use either sp_name or pass two LEX_STRINGs
instead of a Event_timed pointer. This is transitional and eventually the old
functions will be removed. For now DROP EVENT also works, does not need anymore
a parsing object (Event_timed) and definer initialization because everyone who
has EVENT_ACL can drop events, and this is checked on execution time in sql_parse.cc
from the security context, as it should be.


sql/event_data_objects.cc:
  overload few functions
sql/event_scheduler.cc:
  Event_scheduler::drop_event() actually does not need Event_timed object
  but just an identifier, hence pass only sp_name.
  
  Overloaded Event_scheduler::find_event() to work with sp_name object. Eventually
  the old version will be removed. This is being done as transitional step to
  be able to test frequently code.
sql/event_scheduler.h:
  Event_scheduler::drop_event() actually does not need Event_timed object
  but just an identifier, hence pass only sp_name.
  
  Overloaded Event_scheduler::find_event() to work with sp_name object. Eventually
  the old version will be removed. This is being done as transitional step to
  be able to test frequently code.
sql/events.cc:
  Change db_drop_event() not to use Event_timed, either coming from parsing
  or from Event_timed::drop, but use LEX_STRINGs. sp_name is not convinient
  because in Event_timed::drop a temporary object has to be created. Hence, 
  dereference the sp_name in Events::drop_event() and pass the LEX_STRINGs.
sql/events.h:
  Change db_drop_event() not to use Event_timed, either coming from parsing
  or from Event_timed::drop, but use LEX_STRINGs. sp_name is not convinient
  because in Event_timed::drop a temporary object has to be created. Hence, 
  dereference the sp_name in Events::drop_event() and pass the LEX_STRINGs.
sql/events_priv.h:
  Change db_drop_event() not to use Event_timed, either coming from parsing
  or from Event_timed::drop, but use LEX_STRINGs. sp_name is not convinient
  because in Event_timed::drop a temporary object has to be created. Hence, 
  dereference the sp_name in Events::drop_event() and pass the LEX_STRINGs.
sql/sql_parse.cc:
  SQLCOM_DROP_EVENT does not need lex->event_parse_data object and 
  is more like SQLCOM_SHOW_CREATE_EVENT. Therefore, move it to the block that
  handles the latter.
sql/sql_yacc.yy:
  DROP EVENT does not need a parsing object, just a name.
  Store it as lex->spname. Pretty similar handling to the one of
  SHOW CREATE EVENT.

Second cut of separating parsing phase from execution phase
Separate Event_timed from parsing phase and introducing Event_parse_data.


sql/event_data_objects.cc:
  second cut,
  copy Event_timed::init_body() to Event_parse_data::init_body()
  Init the body during parsing, everything else keep as a pointer to
  Item or some other pointer to use for later initialization.
sql/event_data_objects.h:
  get the identifier as sp_name*, later will initialize our structures
sql/events.cc:
  for easy transition add temporarily parse_data, later Event_timed *et will be removed.
  Do slow transition because Event_timed is so tightly integrated that a front-attack
  by removing things from this class was unsuccessful. Do things step by step by eliminating
  dependencies. Hence, the code could be checked with the current test suite too
  (early testing)
