the setting of optimizer switch for table elimination.

The implementation of the virtual method not_null_tables for the class
Item_outer_ref must always return 0.

The problem could be demonstrated with an outer join of two single-row
tables where the values of the join attributes were null. Any query
with such a join could return a wrong result set if the where
condition of the query was not empty. For queries with empty
where conditions the result sets were correct.
This was the consequence of two bugs in the code:
 - Item_equal objects for on conditions of outer joins were
   not built if the processed query had no where condition
 - the check for null values in the code that evaluated constant 
   Item_equal objects was incorrect.
Fixed both above problems.
Added a test case for the bug and adjusted results for some other
test cases.

There are two problems:
1. In simplify_joins function we calculate table dependencies. If STRAIGHT_JOIN hint
is used for whole SELECT we do not count it and as result some dependendecies
might be lost. It leads to incorrect table order which is returned by
join_tab_cmp_straight() function.
2. make_join_statistics() calculate the transitive closure for relations a particular
JOIN_TAB is 'dependent on'.
We aggregate the dependent table_map of a JOIN_TAB by adding dependencies from other
tables which we depend on. However, this may also cause new dependencies to be
available after we have completed processing a certain JOIN_TAB.
Both these problems affect condition pushdown and as result condition might be pushed
into wrong table which leads to crash or even omitted which leads to wrong result.
The fix:
1. Use modified 'transitive closure' algorithm provided by Ole John Aske
2. Update table dependences in simplify_joins according to 
   global STRAIGHT_JOIN hint.
Note: the patch also fixes bugs 46091 & 51492

The algorithm inside restore_prev_nj_state failed to
properly update the counters within the NESTED_JOIN
tree. The counter was decremented each time a table in the
node was removed from the QEP, the correct thing to do being
only to decrement it when the last table in the child node
was removed from the plan. This lead to node counters
getting negative values and the plan thus appeared
impossible. An assertion caught this.

Fixed by not recursing up the tree unless the last table in
the join nest node is removed from the plan

Optimizer erroneously translated LEFT JOIN into INNER JOIN.
It leads to cutting rows with NULL right side. It happens
because Item_row uses not_null_tables() method form the
base(Item) class and does not calculate 'null tables'
properly. The fix is adding calculation of 'not null tables'
to Item_row.

returns incorrect results with where

An outer join of a const table (outer) and a normal table
(inner) with GROUP BY on a field from the outer table would
optimize away GROUP BY, and thus trigger the optimization to
do away with a temporary table if grouping was performed on
columns from the const table, hence executing the query with
filesort without temporary table. But this should not be
done if there is a non-indexed access to the inner table,
since filesort does not handle joins. It expects either ref
access, range ditto or table scan. The join condition will
thus not be applied.

Fixed by always forcing execution with temporary table in
the case of ROLLUP with a query involving an outer join. This
is a slightly broader class of queries than need fixing, but
it is hard to ascertain the position of a ROLLUP field wrt
outer join with current query representation.

  The patch for WL 1563 added a new duplicate key error message so that the
  key name could be provided instead of the key number. But the error code
  for the new message was used even though that did not need to change.

  This could cause unnecessary problems for applications that used the old
  ER_DUP_ENTRY error code to detect duplicate key errors.

* Provide backwards compatibility extension to name resolution of
  coalesced columns. The patch allows such columns to be qualified
  with a table (and db) name, as it is in 4.1.
  Based on a patch from Monty.

* Adjusted tests accordingly to test both backwards compatible name
  resolution of qualified columns, and ANSI-style resolution of
  non-qualified columns.
  For this, each affected test has two versions - one with qualified
  columns, and one without.

sql/sql_base.cc:
  * Applied Monty's patch for backwards compatible name resolution
    of qualified columns. The idea is:
    - When a column is qualified, search for the column in all
      tables/views underlying each natural join. In this case
      natural joins are *not* considered leaves.
    - If a column is not qualified, then consider natural joins
      as leaves, thus directly search the result columns of
      natural joins.
  * Simplified 'find_field_in_tables()' - unified two similar
    loops into one.
sql/table.cc:
  - Removed method & members not needed after Monty's patch.
sql/table.h:
  - Removed method & members not needed after Monty's patch.
tests/mysql_client_test.c:
  Put back old tests to test that coalesced columns of natural joins can be qualified.

"Process NATURAL and USING joins according to SQL:2003".

* Some of the main problems fixed by the patch:
  - in "select *" queries the * expanded correctly according to
    ANSI for arbitrary natural/using joins
  - natural/using joins are correctly transformed into JOIN ... ON
    for any number/nesting of the joins.
  - column references are correctly resolved against natural joins
    of any nesting and combined with arbitrary other joins.

* This patch also contains a fix for name resolution of items
  inside the ON condition of JOIN ... ON - in this case items must
  be resolved only against the JOIN operands. To support such
  'local' name resolution, the patch introduces a stack of
  name resolution contexts used at parse time.

NOTICE:
- This patch is not complete in the sense that
  - there are 2 test cases that still do not pass -
    one in join.test, one in select.test. Both are marked
    with a comment "TODO: WL#2486".
  - it does not include a new test specific for the task

    Name_resolution_context
  - commented old code
  - standardized formatting
sql/mysql_priv.h:

  - added a new procedure for natural join table references,
  - renamed the find_field_in_XXX procedures to clearer names
sql/sp.cc:

  - extra parameter to find_field_in_tables
sql/sql_acl.cc:
  - renamed find_field_in_table => find_field_in_table_ref
  - extra parameter to find_field_in_table_ref
  - commented old code
sql/sql_base.cc:
  This file contains the core of the implementation of the processing
  of NATURAL/USING joins (WL#2486).
  - added many comments to old code
  - refactored the group of find_field_in_XXX procedures, and added a
    new procedure for natural joins. There is one find_field_in_XXX procedure
    per each type of table reference (stored table, merge view, or natural
    join); one meta-procedure that selects the correct one depeneding on the
    table reference; and one procedure that goes over a list of table
    referenes.
  - NATURAL/USING joins are processed through the procedures:
      mark_common_columns, store_natural_using_join_columns,
      store_top_level_join_columns, setup_natural_join_row_types.
    The entry point to processing NATURAL/USING joins is the
    procedure 'setup_natural_join_row_types'.
  - Replaced the specialized Field_iterator_XXX iterators with one
    generic iterator over the fields of a table reference.
  - Simplified 'insert_fields' and 'setup_conds' due to encapsulation of
    the processing of natural joins in a separate set of procedures.

  - Commented old code.
sql/sql_delete.cc:
  - Pass the FROM clause to setup_tables.
sql/sql_help.cc:

    support the list of tables for name resolution -
    context->first_name_resolution_table, and
    table_list->next_name_resolution_table.
    Needed to support an ugly trick to resolve inserted columns only in
    the first table.
  - Added Name_resolution_context::[first | last]_name_resolution_table.
  - Commented old code
sql/sql_lex.cc:
  - set select_lex.parent_lex correctly
  - set correct state of the current name resolution context

    for each new JOIN ... ON, and popped afterwards.
  - Added support for NATURAL/USING joins.
sql/table.cc:
  - Added new class Natural_join_column to hide the heterogeneous
    representation of column references for stored tables and for
    views.
  - Added a new list TABLE_LIST::next_name_resolution_table to
    support name resolution with NATURAL/USING joins. Also added
    other members to TABLE_LIST to support NATURAL/USING joins.
  - Added a generic iterator over the fields of table references
    of various types - class Field_iterator_table_ref
sql/table.h:

  Fix for BUG#8711: "<=>" may have true value for NULL arguments, i.e. it can accept NULL-complemented 
  table rows. This differs from assumptions made in Item_func::not_null_tables(), so add 
  Item_func_equal::not_null_tables().
  Item_func_equal::not_null_tables_cache value doesn't make sense now, but we still let it be
  calculated (and ignore it)

  Corrected table names
sql/item_cmpfunc.h:
  Fix for valgrind failure (unitialized read Item_func_trig_cond->const_item_cache in get_mm_tree):
   Since get_mm_tree can be called for an instance of Item_func_trig_cond, make Item_func_trig_cond::const_item() return false.
   get_mm_tree will assume Item_func_trig_cond are unknown functions and will not build range access plans for them

so we read dependent tables after tables they depend on (this is needed for outer joins)

  Added cases for bugs #6307 and #6460.
sql_select.cc:
  Fixed the problem of bug reports #6307 and #6460.
  The reported wrong result sets were due to the fact that
  the added call of the fix_fields method for the built
  AND condition that joined WHERE and ON conditions
  broke ON expression, as it removed extra AND levels
  in the built condition. 
  It looks like that no attributes of the built condition
  are needed, so we don't have to call fix_fields here.

  AND condition that joined WHERE and ON conditions
  broke ON expression. 
  It looks like that no attributes of the built condition
  are needed, so we don't have to call fix_fields here.
