Refactor the SrcItem object so that information about subqueries is stored in a separately allocated Subquery object. This reduces the memory requirements for SrcItem and makes the code run faster. It also provides an expansion path for subquery processing that does not burden simple queries. The current checking mostly works, but there are still issues that need to be tracked down and fixed.
