Fixed many problems in the code of With_element::check_unrestricted_recursive().

Browse Source 
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.
