messed up
"ROW(...) IN (SELECT ... FROM DUAL)" always returned TRUE.
Item_in_subselect::row_value_transformer rewrites "ROW(...)
IN SELECT" conditions into the "EXISTS (SELECT ... HAVING ...)"
form.
For a subquery from the DUAL pseudotable resulting HAVING
condition is an expression on constant values, so further
transformation with optimize_cond() eliminates this HAVING
condition and resets JOIN::having to NULL.
Then JOIN::exec treated that NULL as an always-true-HAVING
and that caused a bug.
To distinguish an optimized out "HAVING TRUE" clause from
"HAVING FALSE" we already have the JOIN::having_value flag.
However, JOIN::exec() ignored JOIN::having_value as described
above as if it always set to COND_TRUE.
The JOIN::exec method has been modified to take into account
the value of the JOIN::having_value field.

The greedy optimizer tracks the current level of nested joins and the position
inside these by setting and maintaining a state that's global for the whole FROM
clause.
This state was correctly maintained inside the selection of the next partial plan
table (in best_extension_by_limited_search()).
greedy_search() also moves the current position by adding the last partial match
table when there's not enough tables in the partial plan found by
best_extension_by_limited_search().
This may require update of the global state variables that describe the current
position in the plan if the last table placed by greedy_search is not a top-level
join table.
Fixed by updating the state after placing the partial plan table in greedy_search()
in the same way this is done on entering the best_extension_by_limited_search().
Fixed the signature of the function called to update the state :
check_interleaving_with_nj

Table could be marked dependent because it is
either 1) an inner table of an outer join, or 2) it is a part of
STRAIGHT_JOIN. In case of STRAIGHT_JOIN table->maybe_null should not
be assigned. The fix is to set st_table::maybe_null to 'true' only
for those tables which are used in outer join.

Fixed bug when removing a newly inserted record (in case of duplicate key).
The bug caused a crash for rows with several blobs and the first blob was small enough to fit into the head page.
Don't change state_history if nothing changed (speed optimization that also simplifies logic).
Reset state_history if we added/deleted or updated rows without versioning.
Fixed wrong test in trnman_exists_active_transactions() if state is visible or not.
Other bugs fixed:
Fixed wrong argument to (lock->get_status) when we had to wait for TL_WRITE_CONCURRENT_INSERT.
Item_equal::update_used_tables() didn't calculate const_item_cache properly.
Added assert's to detect if join_read_const_table() was called under wrong assumptions..
Fixed that _ma_setup_live_state() is called from thr_lock() instead of handler::external_lock().
This was needed to get versioning information to be setup correctly.
Fixed error in debug binaries during a call to _ma_check_table_is_closed() when another thread was opening/closing a table.
Fixed wrong test when finding right history_state to use.

Added assert's to detect if join_read_const_table() was called under wrong assumptions.
One assert() is disabled for now as Item_equal() doesn't behave as expected.
storage/maria/ha_maria.cc:
Move calling to _ma_setup_live_state() to ma_state.c::_ma_block_get_status()
This was needed as _ma_setup_live_state() needed to know if the table will be used concurrently or not

Fixed bug when removing a newly inserted record (in case of duplicate key).

Without the protection we could get a error in debug binaries during a call to _ma_check_table_is_closed()
storage/maria/ma_delete_table.c:
Removed not used code
storage/maria/ma_rename.c:
Removed not used code
storage/maria/ma_state.c:

Mark in tables->state_current.no_transid if we are using transid's or not.
Don't change state_history if nothing changed (speed optimization that also simplifies logic)
Reset state_history if we added/deleted or updated rows without versioning.
More DBUG_ASSERT's and more DBUG
Updated maria_versioning() to initialize environment before calling _ma_blok_get_status(). This was needed because of the new logic in _ma_block_get_status()
storage/maria/ma_state.h:
