Clean up problems with sublinks + grouping in planner. Not

sure if they are all fixed, because rewriter is now the stumbling block,
but at least some cases work that did not work before.

Create a generic expression-tree-walker subroutine, which
...
will gradually replace all of the boilerplate tree-walk-recursion code that
currently exists in O(N) slightly different forms in N subroutines.
I've had it with adding missing cases to these subroutines...

Change GEQO optimizer to release memory after each gene

is evaluated. This bounds memory usage to something reasonable even
when many tables are being joined.

Rip out QueryTreeList structure, root and branch. Querytree
...
lists are now plain old garden-variety Lists, allocated with palloc,
rather than specialized expansible-array data allocated with malloc.
This substantially simplifies their handling and eliminates several
sources of memory leakage.
Several basic types of erroneous queries (syntax error, attempt to
insert a duplicate key into a unique index) now demonstrably leak
zero bytes per query.

Revise union_planner and associated routines to clean up breakage

now work again. Also, the code is at least somewhat better documented...

Partial fix for copied-plan bugs reported by Hiroshi Inoue:
...
_copyResult didn't copy subPlan structure completely. _copyAgg is still
busted, apparently because of changes from EXCEPT/INTERSECT patch
(get_agg_tlist_references is no longer sufficient to find all aggregates).
No time to look at that tonight, however.
