The fix for bug mdev-4971 not always correctly set the pointers to
inherited multiple equalities in objects of the Item_equal class. 

            ORDER BY does not work

Use "dynamic" row format (instead of "block") for MARIA internal
temporary tables created for cursors.

With "block" row format MARIA may shuffle rows, with "dynamic" row
format records are inserted sequentially (there are no gaps in data
file while we fill temporary tables).

This is needed to preserve row order when scanning materialized cursors.

If rpl_semi_sync_master_timeout is large, calculation of absolute waiting time in semi-sync plugin is inefficient. This error is specific to systems with 64 bit long values (all 64 bit Unixes)
In  rpl_semi_sync_master_timeout has maximal value (= MAX_ULONGLONG), calculating abstime may require  ~ 18 billion subtract operations.

The fix is to use division instead of subtraction-in-a-loop. Also fixed an integer overflow bug.

- YYPARSE_PARAM and YYLEX_PARAM are removed in Bison 3.0. Deprecated
  since Bison 1.875 in favor of %lex-param, %parse-param.
- %parse-param adds an argument to yyerror() as well, updated
  MYSQLerror() accordingly.
- %parse-param allows to declare proper type for argument. That's
  what 99% of this patch is about.

The function propagate_new_equalities() did not updated properly
the references to inherited multiple equalities.

When a non-nullable datetime field is used under an IS NULL predicate
of the WHERE condition in a query with outer joins the remove_eq_conds
function should check whether this field belongs to an inner table
of any outer join that can be, in a general case, a nested outer join.

for dynamic engines (because it only looked at the one-byte code, not at the full
engine name).

that requires MDL_SHARED_NO_READ_WRITE.

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.

Item_cond_or.

don't log it to the error log.

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

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().

- When applying optimization introduced by MDEV-4817, ignore the conditions that have form
  "datetime_not_null_col IS NULL".

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.
