A test case was waiting for a fixed number of seconds for a specific 
state of the slave IO thread to take place.
Fixed by waiting in a loop for that specific thread state instead 
(or timeout).

The SELECT query with more than 31 nested dependent SELECT queries returned
wrong result.

New error message has been added: ER_TOO_HIGH_LEVEL_OF_NESTING_FOR_SELECT.
It will be reported as: "Too high level of nesting for select".

  The Item_sum::register_sum_func method has been modified to return
  TRUE on exceeding of allowed level of SELECT nesting and to report
  corresponding error message.

  Fixed bug #27352.
  Constant definition has been added: maximal allowed level of SELECT nesting.

This patch adds cost estimation for the queries with ORDER BY / GROUP BY
and LIMIT. 
If there was a ref/range access to the table whose rows were required
to be ordered in the result set the optimizer always employed this access
though a scan by a different index that was compatible with the required 
order could be cheaper to produce the first L rows of the result set.
Now for such queries the optimizer makes a choice between the cheapest
ref/range accesses not compatible with the given order and index scans
compatible with it.
