Jussi Saurio ae22468d8b Merge 'Order by heap sort' from Nikita Sivukhin ...

This PR implements simple heap-sort approach for query plans like
`SELECT ... FROM t WHERE ... ORDER BY ... LIMIT N` in order to maintain
small set of top N elements in the ephemeral B-tree and avoid sort and
materialization of whole dataset.
I removed all optimizations not related to this particular change in
order to make branch lightweight.
