Options for the START TRANSACTION statement.
Note that READ ONLY and READ WRITE are logically mutually exclusive.
This is enforced by the parser and depended upon by trans_begin().
We need two flags instead of one in order to differentiate between
situation when no READ WRITE/ONLY clause were given and thus transaction
is implicitly READ WRITE and the case when READ WRITE clause was used
explicitly.
