  Fixed wrong test if log file has increased.
  Don't reset pages_to_flush_before_next_checkpoint as this would cause the checkpoint to happen at next checkpoint interval

Fixed that automatic killing of delayed insert thread (in flush, alter table etc) will not abort auto-repair of MyISAM table.
Give more information when finding an error in a MyISAM table.
When killing system thread, use KILL_SYSTEM_THREAD instead of KILL_CONNECTION to make it easier to ignore the signal in sensitive context (like auto-repair)
Added new kill level: KILL_SERVER that will in the future to be used to signal killed by shutdown.
Add more warnings about killed connections when warning level > 3

  Removed nonsence check "if (sort_param->read_cache.error < 0)" in repair.
storage/myisam/myisamchk.c:
  Added counting of notes printed
storage/pbxt/src/thread_xt.cc:
  Better error message.

The problem was that optimization code did not take into account later feature when instad of NOT before BETWEEN it has negated flag into the Item_func_between inherited from Item_func_neg_opt. So optimizer tried process NOT BETWEEN as BETWEEN.

The patch just switches off the optimisation for NOT BETWEEN as it was before when NOT function was really used.

  
  ALL subquery should return TRUE if subquery rowa set is empty independently
  of left part.  The problem was that Item_func_(eq,ne,gt,ge,lt,le) do not
  call execution of second argument if first is NULL no in this case subquery
  will not be executed and when Item_func_not_all calls any_value() of the
  subquery or aggregation function which report that there was rows. So for
  NULL < ALL (SELECT...) result was FALSE instead of TRUE.
  
  Fix is just swapping of arguments of Item_func_(eq,ne,gt,ge,lt,le) (with
  changing the operation if it is needed) so that result will be the same
  (for examole a < b is equal to b > a). This fix exploit the fact that
  first argument will be executed in any case.

Added --debug-assert-on-error variable which, if set, will cause safe_mutex to assert if it founds an error.

include/my_sys.h:
  Added my_assert_on_error
mysys/my_static.c:
  Added my_assert_on_error
mysys/thr_mutex.c:
  Assert when found wrong mutex usage if my_assert_on_error is set
sql/mysqld.cc:
  Added setting of my_assert_on_error

For ANY subqueries NULLs should be ignored (if there is other values) when finding max min.
For ALL subqueries NULLs should be saved if they found.

Optimisation for ALL suqbueries if NULL is possible in the SELECT list with max/min aggregate function switched off.

Some test changed where NULL is not used but optimization with max/min aggregate function important so NOT NULL added.

mysql-test/r/explain.result:
  Forced old optimization.
mysql-test/r/subselect.result:
  Forced old optimization.
  
  New test suite.
mysql-test/t/explain.test:
  Forced old optimization.
mysql-test/t/subselect.test:
  Forced old optimization.
  
  New test suite.
sql/item_subselect.cc:
  Store converted subquery type.
  
  Switch off aggregate function optimisation for ALL and nulls.
