SHOW TABLE STATUS now shows if an Aria table is transactional or not
This change also affects information_schema.tables
The create table option "transactional=0 | 1" is now always shown for
storage engines that supports both transactional/crash safe tables and
non transactional tables.
Before this patch the transactional=... option was only shown if the user
specified transactional=... in the CREATE TABLE or ALTER TABLE statement.
The reason for the change was to be able to make it easy to know if an Aria
table is transactional or not.
