Sorting is now done using a sorting index rather than loading the entire

result set into memory and doing a merge sort. The old merge sort technique
was a carry-over from SQLite version 1. The new method uses a bounded amount
of memory and scales to much larger result sets. There are still errors:
some 39 regression tests fail. (CVS 2653)
