acaa584c55 Fix for bug#22338 "Valgrind warning: uninitialized variable in 
create_tmp_table()".

The fix for bug 21787 "COUNT(*) + ORDER BY + LIMIT returns wrong
result" introduced valgrind warnings which occured during execution
of information_schema.test and sp-prelocking.test in version 5.0.
There were no user visible effects.

The latter fix made create_tmp_table() dependant on
THD::lex::current_select value. Valgrind warnings occured when this
function was executed and THD::lex::current_select member pointed
to uninitialized SELECT_LEX instance.

This fix tries to remove this dependancy by moving some logic
outside of create_tmp_table() function.

d3d3cef88c Fixed bug #21493: crash for the second execution of a function 
containing a select statement that uses an aggregating IN subquery.
Added a parameter to the function fix_prepare_information 
to restore correctly the having clause for the second execution.
Saved andor structure of the having conditions at the proper moment
before any calls of split_sum_func2 that could modify the having structure
adding new Item_ref objects. (These additions, are produced not with 
the statement mem_root, but rather with the execution mem_root.)

7194b6d75a This changes the order of the universe, black is now the new white. 
In practice this means that handlerton is now created by the server and is passed to the engine. Plugin startups can now also control how plugins are inited (and can optionally pass values). Bit more flexibility to those who want to write plugin interfaces to the database.

equal constant under any circumstances.
In fact this substitution can be allowed if the field is
not of a type string or if the field reference serves as 
an argument of a comparison predicate.

Select_type in the EXPLAIN output for the query SELECT * FROM t1 was
'SIMPLE', while for the query SELECT * FROM v1, where the view v1
was defined as SELECT * FROM t1, the EXPLAIN output contained 'PRIMARY'
for the select_type column.

02e194cea2 Fix for BUG#21787: COUNT(*) + ORDER BY + LIMIT returns wrong result 
The problem was due to a prior fix for BUG 9676, which limited
the rows stored in a temporary table to the LIMIT clause. This
optimization is not applicable to non-group queries with aggregate
functions. The fix disables the optimization in this case.

0e96978cf6 Fixed bug #16081: row equalities were not taken into 
account by the optimizer.
Now all row equalities are converted into conjunctions of
equalities between row elements. They are taken into account
by the optimizer together with the original regular equality
predicates.
