SQLite implementation of \Drupal\Core\Database\Statement.
The PDO SQLite driver only closes SELECT statements when the PDOStatement destructor is called and SQLite does not allow data change (INSERT, UPDATE etc) on a table which has open SELECT statements. This is a user-space mock of PDOStatement that buffers all the data and doesn't have those limitations.
