Fix for BUG#36104 "INFORMATION_SCHEMA.TABLES shows TRANSACTIONAL=1 twice in CREATE_OPTIONS"

mysql-test/r/maria.result:
  result; before the bugfix it would be "TRANSACTIONAL=1 transactional=1"
mysql-test/t/maria.test:
  test for BUG#36104 "INFORMATION_SCHEMA.TABLES shows TRANSACTIONAL=1 twice in CREATE_OPTIONS"
sql-bench/example:
  doblewrite->doublewrite
sql/mysqld.cc:
  fix of a wrong 5.1->maria merge of the past
sql/sql_insert.cc:
  removing my old idea of disabling transactionality in CREATE SELECT:
  1) it caused bugs because re-enabling (ha_enable_transaction()) causes implicit commit, so in complex cases
  like "CREATE SELECT some_func())", where some_func() would want to insert two rows in another table, and fail on the second row, the implicit commit would commit the inserted row, while it should roll back.
  2) it's not needed anymore, because CREATE SELECT uses bulk insert, and Maria has transactionality disabled by
  bulk insert.
sql/sql_show.cc:
  This was duplicate code, causing BUG#36104 "INFORMATION_SCHEMA.TABLES shows TRANSACTIONAL=1 twice in CREATE_OPTIONS"
