Improve comments about btree's use of ScanKey data structures: there
are two basically different kinds of scankeys, and we ought to try harder to indicate which is used in each place in the code. I've chosen the names "search scankey" and "insertion scankey", though you could make about as good an argument for "operator scankey" and "comparison function scankey".
