[SPARK-4480] Avoid many small spills in external data structures (again)
I accidentally closed the PR at #3353 and can't re-open it for some reason.
The changes here are identical the the ones there. I'll merge this into master
and 1.2 once the tests pass.

Fix tests
Unfortunately we have to expose the config here to keep the
