to fix a problem with the test case for bug#42116. 

- Moved some code from innodb_plugin to xtradb, to ensure that all tests runs
- Did changes in pbxt and maria storage engines becasue of changes in thd->query
- Reverted wrong code in sql_table.cc for how ROW_FORMAT is used.

Todo before joining with main 5.1 tree:
- Join test fails (Igor to investigate)
- mysql-test-run shows warnings from tests; Some suppression rule is not working (Kristian to investiage)
- Run through all buildbots



sql/sql_table.cc:
  Reverted code for ROW_FORMAT is used. We must set the HA_CREATE_USED_ROW_FORMAT flag in alter table
  to signal the handler that it should not change row_type in update_create_info() (as happens for SHOW CREATE).
storage/maria/ha_maria.cc:
  Update for change in defintion of thd->query
storage/myisam/mi_check.c:
  Simplify code
storage/pbxt/src/discover_xt.cc:
  Update for change in defintion of thd->query

Bug#41756 "Strange error messages about locks from InnoDB".
      
In JT_EQ_REF (join_read_key()) access method, 
don't try to unlock rows in the handler, unless certain that 
a) they were locked
b) they are not used.

Unlocking of rows is done by the logic of the nested join loop,
and is unaware of the possible caching that the access method may
have. This could lead to double unlocking, when a row
was unlocked first after reading into the cache, and then 
when taken from cache, as well as to unlocking of rows which
were actually used (but taken from cache).
      
Delegate part of the unlocking logic to the access method,
and in JT_EQ_REF count how many times a record was actually 
used in the join. Unlock it only if it's usage count is 0.

Implemented review comments.

            values return too many records

WHERE clauses with "outer_value_list NOT IN subselect" were
handled incorrectly if the outer value list contained multiple 
items where at least one of these could be NULL. The first 
outer record with NULL value was handled correctly, but if a 
second record with NULL value existed, the optimizer would 
choose to reuse the result it got on the last execution of the 
subselect. This is incorrect if the outer value list has 
multiple items.
     
The fix is to make Item_in_optimizer::val_int (in 
item_cmpfunc.cc) reuse the result of the latest execution
for NULL values only if all values in the outer_value_list 
are NULL.

branches/zip: This test has been problematic for sometime now. The underlying
bug is that the data dictionaries get out of sync. In the AUTOINC code we
try and apply salve to the symptoms. In the past MySQL made some unrelated
change and the dictionaries stopped getting out of sync and this test started
to fail. Now, it seems they have reverted that changed and the test is
passing again. I suspect this is not he last time that this test will change.

branches/zip: Fix corruption of buf_pool->LRU_old and improve debug assertions.
This was reported as Issue #381.

buf_page_set_old(): Assert that blocks may only be set old if
buf_pool->LRU_old is initialized and buf_pool->LRU_old_len is nonzero.
Assert that buf_pool->LRU_old points to the block at the old/new boundary.

buf_LRU_old_adjust_len(): Invoke buf_page_set_old() after adjusting
buf_pool->LRU_old and buf_pool->LRU_old_len, in order not to violate
the added assertions.

buf_LRU_old_init(): Replace buf_page_set_old() with a direct
assignment to bpage->old, because these loops that initialize all the
blocks would temporarily violate the assertions about
buf_pool->LRU_old.

buf_LRU_remove_block(): When setting buf_pool->LRU_old = NULL, also
clear all bpage->old flags and set buf_pool->LRU_old_len = 0.

buf_LRU_add_block_to_end_low(), buf_LRU_add_block_low(): Move the
buf_page_set_old() call later in order not to violate the debug
assertions.  If buf_pool->LRU_old is NULL, set old=FALSE.

buf_LRU_free_block(): Replace the UNIV_LRU_DEBUG assertion with a
dummy buf_page_set_old() call that performs more thorough checks.

buf_LRU_validate(): Do not tolerate garbage in buf_pool->LRU_old_len
even if buf_pool->LRU_old is NULL.  Check that bpage->old is monotonic.

buf_relocate(): Make the UNIV_LRU_DEBUG checks stricter.

buf0buf.h: Revise the documentation of buf_page_t::old and
buf_pool_t::LRU_old_len.
