The order of acquiring LOCK_mysql_create_db
and wait_if_global_read_lock() was wrong. It could happen
that a thread held LOCK_mysql_create_db while waiting for
the global read lock to be released. The thread with the
global read lock could try to administrate a database too.
It would first try to lock LOCK_mysql_create_db and hang...
The check if the current thread has the global read lock
is done in wait_if_global_read_lock(), which could not be
reached because of the hang in LOCK_mysql_create_db.
Now I exchanged the order of acquiring LOCK_mysql_create_db
and wait_if_global_read_lock(). This makes
wait_if_global_read_lock() fail with an error message for
the thread with the global read lock. No deadlock happens.

- This changeset also changes the executor so its quite more stable now.
Stressing test case added that executes ~800 events per second and dropping
hundreds of events at once using DROP DATABASE.
(with fixes after review of JimW)
(with fixes after review of Serg)
mysql-test/r/events.result:
update results after TRIGGER_ACL was added
mysql-test/t/events.test:
-redundant line
sql/event.cc:
Implemented evex_db_drop_events() which drops all events
from a specific database. Needed for SQLCOM_DROP_DATABASE
sql/event.h:
- protect the event better (see the changes to event_executor.cc
and event.cc). An event object could be used in a spawned thread
before it's executed but till now the object is marked as being
executed when the anonymous sp_head is executed. However, there are
timeframes before and after that during which the event is not marked
as executed and other thread may delete the object -> so we end with
a nirvana pointer.
sql/event_executor.cc:
- extract some of the code executed in the main thread to a function. Too long
functions are bad for the overview.
- prepend all information/error messages to the console with "SCHEDULER:" for
better overview, and easied searching in the log tables.
sql/event_priv.h:
- change the name, of evex_db_find_event_by_name() and don't
used C++ features like function overloading
- define consts for result returned from event_timed::spawn_now()
sql/event_timed.cc:
- add few methods related to event execution.
now the event spawns the worker thread and
passes itself as parameter. This way it locks itself for exectution
first and then spawning -> no race condition. When the worker thread
has finished working with the reference it calls back
event_timed::spawn_thread_finish() to unlock itself.
sql/sql_db.cc:
- call evex_drop_db_events() on DROP DATABASE
