WL#3337 (Events new infrasctructure)

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)

BitKeeper/etc/ignore:
  Added libmysql/viosocket.o.6WmSJk libmysqld/event_data_objects.cc libmysqld/event_db_repository.cc libmysqld/event_queue.cc server-tools/instance-manager/net_serv.cc to the ignore list
sql/share/errmsg.txt:
  remove this message, not used and needed for now
sql/sql_lex.h:
  for easy transition add temporarily parse_data, later Event_timed *et will be removed.
