Fixed many problems in the code of With_element::check_unrestricted_recursive().
Added the check whether there are set functions in the specifications of recursive CTE.
Added the check whether there are recursive references in subqueries.
Introduced boolean system variable 'standards_compliant_cte'. By default it's set to 'on'.
When it's set to 'off' non-standard compliant CTE can be executed.
