  Post-merge fixes for nested joins. 
  The join_tab_cmp function in sql_select has been changed
sql_select.cc:
  Post-merge fixes for nested joins.
  Avoided re-execution of eliminate_not_funcs and simplify_joins
  in optimize_cond.
  Changed the join_tab_cmp function to take into account
  the dependent relation.
sql_lex.cc, sql_lex.h:
  Added the first_cond_optimization flag to st_select_lex to avoid
  re-execution of some optimizations in optimize_cond.
sql_base.cc:
  Post-merge fixes for nested joins. 
  Fixed problems with a proper column list substituted for '*' in
  queries with natural joins.

  Nested joins: review modifications.

If cost(full_scan_on_shortest_covering_index) < cost(best_range_scan) <  cost(full_table_scan)
  use full_scan_on_shortest_covering_index
(before this fix best_range_scan was used)

It's not possible to quote the definition according to the current sql_mode
setting, so instead we use the setting stored with the SP (that's how it's
parsed anyway), and show this setting in the SHOW CREATE output.

This fixes part of BUG#3229: Stored procedure comment causes packets out of order.

Typo bug fixed in multitable update
