Fixed bug #27229: crash when a set function aggregated in outer
context was used as an argument of GROUP_CONCAT.
Ensured correct setting of the depended_from field in references
generated for set functions aggregated in outer selects.
A wrong value of this field resulted in wrong maps returned by
used_tables() for these references.
Made sure that a temporary table field is added for any set function
aggregated in outer context when creation of a temporary table is
needed to execute the inner subquery.
mysql-test/r/subselect.result:
Added a test case for bug #27229.
mysql-test/t/subselect.test:
Added a test case for bug #27229.

generated for set functions aggregated in outer selects.
sql/item_sum.cc:
Fixed bug #27229: crash when a set function aggregated in outer
context was used as an argument of GROUP_CONCAT.
Added the field aggr_sel to the objects of the class Item_sum.
In any Item_sum object created for a set function this field
has to contain a pointer to the select where the set function
is aggregated.
sql/item_sum.h:
Fixed bug #27229: crash when a set function aggregated in outer
context was used as an argument of GROUP_CONCAT.
Added the field aggr_sel to the objects of the class Item_sum.
In any Item_sum object created for a set function this field
has to contain a pointer to the select where the set function
is aggregated.
Added a method that says whether a set function is aggregated
in outer context and, if so, returns the aggregating select.
Removed the field nest_level_tables_count introduced by the
patch for bug 24484 as aggr_sel->join->tables contains the
sane number.
sql/sql_base.cc:
Fixed bug #27229: crash when a set function aggregated in outer
context was used as an argument of GROUP_CONCAT.
Added the field aggr_sel to the objects of the class Item_sum.
Removed changes introduced by the patch for bug 24484 as
the field leaf_count of the THD class is not used anymore.
sql/sql_class.h:
Fixed bug #27229: crash when a set function aggregated in outer
context was used as an argument of GROUP_CONCAT.
Added the field aggr_sel to the objects of the class Item_sum.

Fixed bug #27229: crash when a set function aggregated in outer
context was used as an argument of GROUP_CONCAT.
Added the field aggr_sel to the objects of the class Item_sum.
Removed changes introduce by the patch for bug 24484 as
the field leaf_count of the THD class is not used anymore.
sql/sql_select.cc:
Fixed bug #27229: crash when a set function aggregated in outer
context was used as an argument of GROUP_CONCAT.
When creating a temporary table a field is added in it for any
set function aggregated in outer context.
