sql/item_subselect.cc:
  Fixed bug #24670: optimizations that are legal only for subqueries without tables
  and no WHERE condition were applied for any subquery without tables.
  
  Removed an assertion that caused an abort for subqueries without tables and no 
  WHERE condition. 
  Blocked substitution of a single-row subquery without tables for the constant 
  row from its select list when the subquery contained a WHERE condition.
  This optimization is valid only for subquries without tables with no conditions.
  Any subquery without tables with WHERE clause returns NULL if the WHERE condition
  is FALSE. Erroneously it was always considered as non-nullable that could trigger 
  another optimization concerning IS NULL predicates which is applicable only for 
  non-nullable expressions and ultimately led to a wrong result returned by the outer
  query.
  Added a proper implementation of the virtual method may_be_null for class 
  subselect_single_select_engine.
sql/item_subselect.h:
  Fixed bug #24670: optimizations that are legal only for subqueries without tables
  and no WHERE condition were applied for any subquery without tables.
  Made method may_by_null for class subselect_engine vvirtual.

  New BitKeeper file ``mysql-test/std_data/bad_gis_data.dat''

The problem is that the GEOMETRY NOT NULL can't automatically set
any value as a default one. We always tried to complete LOAD DATA
command even if there's not enough data in file. That doesn't work
for GEOMETRY NOT NULL. Now Field_*::reset() returns an error sign
and it's checked in mysql_load()

This error is displayed anytime the SELECT statement needs a temp table to
return correct results because the object (select_dumpvar) that represents
variables named in the INTO clause stored the results before the temp
table was considered.  The problem was fixed by creating the necessary
Item_func_set_user_var objects once the correct data is ready.

mysql-test/t/distinct.test:

  - Added Select Into Outfile variant tests also.
sql/sql_class.cc:
  Bug#20836 Selecting into variables results in wrong results being returned
  - The select_dumpvar variable created a Item_func_set_user_var too early
  and once set, it was not possible to change.  The Item_func_set_user_var
  is now created once the final results are available.
sql/sql_class.h:
  Bug#20836 Selecting into variables results in wrong results being returned

After that it will by default use log tables. That setting can be overruled
by adding a -master.opt file like mysql_client_test has.
