- In ha_partition, make ordered index reads return rows in rowid order
  when index columns are the same.

  message:
    Enable rpl_row_create_table (no reason to keep this disabled anymore)

Still fails (in --ps), no reason to enable it if it is not fixed.

(just to have the test in the tree when we merge the upstream fix)

Don't ignore the error from st_select_lex_unit::optimize()

as it was supposed to be in bug#11747970, don't fake an error.
(this kill can be useful for other bugs too)

Deadlock happened due to mixed lock order.
CREATE/DROP function: wrlock(THR_LOCK_udf) -> lock(LOCK_open)
SELECT from view: lock(LOCK_open) -> rdlock(THR_LOCK_udf)

Fixed CREATE/DROP function so that LOCK_open does not intersect with
wrlock(THR_LOCK_udf).

10.0 is not affected: it doesn't hold LOCK_open while opening view.

(mainly by backporting 5.5. changes)

mysql-test/suite/maria/t/distinct.test:
  Remove the test that requires SSL. One test case for a bug is enough.
sql/scheduler.cc:
  make it the same as in 5.5
storage/innodb_plugin/row/row0mysql.c:
  make it the same as in 5.5
storage/innodb_plugin/row/row0sel.c:
  make it the same as in 5.5
storage/xtradb/row/row0mysql.c:
  make it the same as in 5.5
storage/xtradb/row/row0sel.c:
  make it the same as in 5.5

fix the NAME_CONST check to only allow literals, negated literals, and literals with
the explicit collation.

Fixed error processing in find_order_in_list(): if an error reported to user there is no sens to continue.

This is needed to be able to ignore executable comments from version 10.0.

Problem was that we used cache_table in some cases where it was not initialized

mysql-test/r/func_group.result:
  Added test case
mysql-test/t/func_group.test:
  Added test case
sql/item.cc:
  Don't use cached_table if not set
sql/item_sum.cc:
  Don't use cached_table

(Had accidently been set to 56 seconds in some merge)


sql/sys_vars.cc:
  Set default progress report time to 5 seconds

Fix for MDEV-5629: Failing assertion: state == TRX_STATE_NOT_STARTED on concurrent CREATE OR REPLACE and transactional UPDATE

mysql-test/suite/innodb/r/row_lock.result:
  Test case for MDEV-5629
mysql-test/suite/innodb/t/row_lock.test:
  Test case for MDEV-5629
sql/filesort.cc:
  Don't call unlock_row() in case of errors

Destroying rw_lock twice by resize() prevented.

The method Item_field::update_table_bitmaps() should not try
to mark the bit for a self-referencing virtual column.

- Let cleanup_empty_jtbm_semi_joins() walk into semi-join nests.

The field JOIN::select_lex->where should be updated after the call
of remove_eq_conds() in the function make_join_statistics(). This
matters for subselects.

appears to be unset, or when it contains 'root' even though the user
does not have real root permissions

Set of JOIN_TYPE_OUTER made only once to avoid interference with optimization joins which made only once per query.
