sql/sql_base.cc:
  More DBUG
sql/sql_class.cc:
  Changed that thd_sqlcom_can_generate_row_events() does not report that CREATE OR REPLACE is generating row events.
  This is safe as this function is only used by InnoDB/XtraDB to check if a query is generating row events as part of another transaction. As CREATE is always run as it's own transaction, this isn't a problem.
  This fixed MDEV-6525.
sql/sql_table.cc:
  Remember if reopen_tables() generates an error (which can only happen in case of KILL).
  This fixed MDEV-6560
