This patch makes the relationship between Event_scheduler and Event_queue
unidirectional from the former to the latter.




The change is that the conditional on which the scheduler sleeped has been
moved to the Event_queue and the latter does not call anymore
Event_scheduler::queue_changed(), which in turn has be removed.

const for two parameters.

There is an existing macros for initializing LEX_STRINGs
with constant strings -> C_STRING_WITH_LEN. Change existing code to use it.
(char *) STRING_WITH_LEN -> C_STRING_WITH_LEN

Shift from direct usage of (char *) with STRING_WITH_LEN
to C_STRING_WITH_LEN

Post-review fixes. Mostly whitespace, int-to-bool return value, fixed comments

in their name.

The problem was that IM-tests contained grep-statements with too wide
patterns. The fix is to make these patterns more restrictive. Only IM-tests
have been fixed, no code has been touched.

create function func() returns char(10) binary ...
is no more possible. This will be reenabled when 
bug 2676 "DECLARE can't have COLLATE clause in stored procedure"
is fixed.

Fix after 2nd review
