MDEV-5337: Wrong result in mariadb 5.5.32 with ORDER BY + LIMIT when index_condition_pushdown=on - in test_if_skip_sort_order(), correct the condition under which we have the code that restores the previously pushed index condition.

The crash happened because Item_func_monthname was derived from Item_func_month, so Item_func_monthname::is_null() did not work fine. Backporting a change from 5.5: Item_func_monthname is now derived from Item_str_func.

- convert_subq_to_sj() must connect child select's tables into parent select's TABLE_LIST::next_local chain. - The problem was that it took child's leaf_tables.head() which is different. This could cause certain tables (in this bug's case, child select's non-merged semi-join) not to be present in TABLE_LIST::next_local chain. Which would cause non-merged semi-join not to be initialized in setup_tables(), which would lead to NULL pointer dereference.

THD::thd->activate_stmt_arena_if_needed() should be used to temporary activating statement arena instead of direct usage of THD::set_n_backup_active_arena() because possible such scenario: 1) func1 saves current arena and activates copy1 of statement arena 2) func2 saves copy1 of statement arena setup by func1 and activates copy2 3) some changes made for copy 2 4) func2 stores changed copy2 back to statenet arena and activates copy1 5) func1 store unchanged copy1 back to statemnt arena (rewrite changed copy 2 so changes become lost) and activates arena which was before.

When marking used columns the function find_field_in_table_ref() erroneously called the walk method for the real item behind a view/derived table field with the second parameter set to TRUE. This erroneous code was introduced in 2006.

The earlier pushed fix for the bug was incomplete. It did not remove the main cause of the problem: the function remove_eq_conds() removed always true multiple equalities from any conjunct, but did not adjust the list of them stored in Item_cond_and::cond_equal.current_level. Simplified the test case for the bug and moved it to another test file. The fix triggered changes in EXPLAIN EXTENDED for some queries.
