 Description   

It would be nice to have a utility method in \Doctrine\Dbal\Driver\ResultStatement to properly retrieve the result column names.

Currently, we have to rely on somthing like
$columnNames = array_keys($statement->fetch(\PDO::FETCH_ASSOC));

Problem: It does not work with empty result-sets, and more checks should be performed to handle these.

With PDO, http://www.php.net/manual/en/pdostatement.getcolumnmeta.php could be used to properly retrieve names.

For Sqlite3 it is easy, http://www.php.net/manual/en/sqlite3result.columnname.php

For Mysql, http://www.php.net/manual/en/mysqli-result.fetch-fields.php would do the trick
