Implementation of WL#2486 -
"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".

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.
sql/sql_class.h:

- Pass the FROM clause to setup_tables.

- Changed the code that saves and restores the current context to
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.

- Commented old code
sql/sql_lex.cc:
- set select_lex.parent_lex correctly

- Added support for a stack of name resolution contexts needed to
implement name resolution for JOIN ... ON. A context is pushed
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
