in the MariaDB optimizer sense.

While it is stable on itself, the MariaDB integration
within 5.5 series is rather new.

It's safe to delete from HASH when traversing it *backwards*, but not *forwards*.

The fix for mdev-4420 was not quite correct. This patch corrects it.

  Set thd->first_successful_insert_id_in_prev_stmt_for_binlog when setting thd->first_successful_insert_id_in_prev_stmt.
  This is required to get last_insert_id() replicated.
  This is analog to how read_first_successful_insert_id_in_prev_stmt() works.
sql/rpl_utility.cc:
  Added DBUG_PRINT

When in function remove_eq_conds() a sub-formula of the processed condition
is replaced for another formula we should ensure that in the resulting
formula AND/OR levels must alternate.

The patch to fix mdev-4418 turned out to be incorrect.
At the substitution of single row tables in make_join_statistics()
the used multiple equalities may change and references to the new multiple
equalities must be updated. The function remove_eq_conds() takes care of it and
it should be called right after the substitution of single row tables.
Calling it after the call of make_join_statistics was a mistake.

Made sure that degenerate conjunctions/disjunctions are obtained from
AND/OR conditions.

The code of JOIN::optimize that performed substitutions for the best equal
field in all ref items did not take into account that a multiple equality
could contain the result of the single-value subquery if the subquery is
inexpensive. This code was corrected.
Also made necessary corresponding corrections in the code of make_join_select().

Fix two problems in table elimination code:
- Before marking a "value" as bound, check if it is already bound. Marking the 
  same value as bound twice could confuse a module that depends on this value, 
  because Dep_module_XXX use counters to know when they become bound.

- When checking whether field is part of a key, ignore "extended keys" property.
