The optimizer transforms DISTINCT into a GROUP BY
when possible.
It does that by constructing the same structure
(a list of ORDER instances) the parser makes when
parsing GROUP BY.
While doing that it also eliminates duplicates.
But if a duplicate is found it doesn't advance the
pointer to ref_pointer array, so the next
(and subsequent) ORDER structures point to the wrong
element in the SELECT list.
Fixed by advancing the pointer in ref_pointer_array
even in the case of a duplicate.

Problem: setting/displaying @@LC_TIME_NAMES didn't distinguish between
GLOBAL and SESSION variable types - always SESSION variable
was set/shonw.
Fix: set either global or session value.
Also, "mysqld --lc-time-names" was added to set "global default" value.

NO_AUTO_VALUE_ON_ZERO mode.
The table->auto_increment_field_not_null variable wasn't reset after
reading a row which may lead to inserting a wrong value to the auto-increment
field to the following row.
The table->auto_increment_field_not_null variable is reset now right after a
row is being written in the read_fixed_length() and the read_sep_field()
functions.
Removed wrong setting of the table->auto_increment_field_not_null variable in
the read_sep_field() function.

NO_AUTO_VALUE_ON_ZERO mode.

This will hopefully fix events.test failure on vmware-win32,
where scheduling is very primitive.
mysql-test/t/events_scheduling.test:
This test case has no races now and can be enabled under valgrind.
sql/event_scheduler.cc:
Make Event Scheduler thread shutdown more synchronous: report
successful shutdown only after having removed the scheduler
thread from the global list of threads.
This ensures that after the scheduler has been stopped, its
thread is not present in SHOW PROCESSLIST output.
