If elements a not top-level IN subquery were accessed by an index and 
the subquery result set included  a NULL value then the quantified
predicate that contained the subquery was evaluated to NULL when 
it should return a non-null value.

   When resolving unqualified name references MySQL was not
   checking what is the item type for the reference. Thus
   e.g a string literal item that has by convention a name
   equal to its string value will also work as a reference to 
   a SELECT list item or a table field.
   Fixed by allowing only Item_ref or Item_field to referenced by
   (unqualified) name.

This is addition to fix for bug21617. Valgrind reports an error when
opening merge table that has underlying tables with less indexes than
in a merge table itself.

Copy at most min(file->keys, table->key_parts) elements from rec_per_key array.
This fixes problems when merge table and subtables have different number of keys.

Though this is not storage engine specific problem, I was able to
repeat this problem with BDB and NDB engines only. That was the
reason to add a test case into ndb_update.test. As a result
different bad things could happen.

BDB has removed duplicate rows which is not expected.
NDB returns an error.

For multi table update notify storage engine about UPDATE IGNORE
as it is done in single table UPDATE.
