David Rowley 8ee9c25087 Simplify partial path generation in GROUP BY/ORDER BY 
Here we consolidate the generation of partial sort and partial incremental
sort paths in a similar way to what was done in 4a29eabd1.  Since the cost
penalty for incremental sort was removed by that commit, there's no
point in creating a sort path on the cheapest partial path if an
incremental sort could be done instead.

This has the added benefit of reducing the amount of code required to
build these paths.

and functions.  This distribution also contains C language bindings.
