Igor Babaev e57bb1f76c MDEV-19258 RIGHT JOIN hangs in MariaDB ...

This patch corrects the patch for the bug 10006. The latter incorrectly
calculates the attribute TABLE_LIST::dep_tables for inner tables
of outer joins that are to be converted into inner joins.
As a result after the patch some valid join orders were not evaluated
and the optimizer could choose an execution plan that was far from
being optimal.
