The bug caused wrong result sets for union constructs of the form
(SELECT ... ORDER BY order_list1 [LIMIT n]) ORDER BY order_list2.
For such queries order lists were concatenated and limit clause was
completely neglected.
mysql-test/r/order_by.result:
Added a test case for bug #18767.
mysql-test/t/order_by.test:
Added a test case for bug #18767.
sql/sql_lex.h:

sql/sql_parse.cc:
Fixed bug #18767.
Placed the code the created a fake SELECT_LEX into a separate function.
sql/sql_select.cc:
Fixed bug #18767.
Changed the condition on which a SELECT is treated as part of a UNION.
The SELECT in
(SELECT ... ORDER BY order_list1 [LIMIT n]) ORDER BY order_list2
now is handled in the same way as the first SELECT in a UNION
sequence.
sql/sql_union.cc:
Fixed bug #18767.
Changed the condition at which a SELECT is treated as part of a UNION.
The SELECT in
(SELECT ... ORDER BY order_list1 [LIMIT n]) ORDER BY order_list2
now is handled in the same way as the first SELECT in a UNION
sequence.
sql/sql_yacc.yy:
Fixed bug #18767.
Changed the condition at which a SELECT is treated as part of a UNION.
The SELECT in
(SELECT ... ORDER BY order_list1 [LIMIT n]) ORDER BY order_list2
now is handled in the same way as the first SELECT in a UNION
sequence. In the same way is handled the SELECT in
(SELECT ... LIMIT n) ORDER BY order list.
Yet if there is neither ORDER BY nor LIMIT in the single-select
union construct
(SELECT ...) ORDER BY order_list
then it is still handled as simple select with an order clause.
- Fixed some error condtion when handling dates with 'T'
- Added extra test for bug #11867 (Wrong result with "... WHERE ROW( a, b ) IN ( SELECT DISTINCT a, b WHERE ...)" to show it's not yet fixed

Now thd->mem_root is a pointer to thd->main_mem_root and THR_MALLOC is a pointer to thd->mem_root.
This gives us the following benefits:
- Allow us to easily detect if arena has already been swapped before (this fixes a bug in setup_conds() where arena was swaped twice in some cases)
- Faster swaps of arenas (as we don't have to copy the whole MEM_ROOT)
- We don't anymore have to call my_pthread_setspecific_ptr(THR_MALLOC,...) to change where memory is alloced. Now it's enough to set thd->mem_root

selected items is represented as a List<Item_field>, where each
Item_field points to a field of temporary table.
But the temporary table is created anew on each execution of the prepared
statement. So on each subsequent execution we should reset Item_field
items to point to fields from freshly-created temporary table.
sql/table.h:

This is a bug number #5879.
a second time". The bug was caused by incompatibility of
negations elimination algorithm and PS: during first statement
execute a subtree with negation was replaced with equivalent
subtree without NOTs.
The problem was that although this transformation was permanent,
items of the new subtree were created in execute-local memory.
The patch adds means to check if it is the first execute of a
prepared statement, and if this is the case, to allocate items
in memory of the prepared statement.
The implementation:
- backports Item_arena from 5.0
- adds Item_arena::is_stmt_prepare(),
Item_arena::is_first_stmt_execute().
- deletes THD::allocate_temporary_pool_for_ps_preparing(),
THD::free_temporary_pool_for_ps_preparing(); they
were redundant.
and adds a few invariants:
- thd->free_list never contains junk (= freed items)
- thd->current_arena is never null. If there is no
prepared statement, it points at the thd.
The rest of the patch contains mainly mechanical changes and
cleanups.
