queue: entirely rework parallel system

This removes our dependency on padata and moves to a different mode of
multiprocessing that is more efficient.

This began as Samuel Holland's GSoC project and was gradually
reworked/redesigned/rebased into this present commit, which is a
combination of his initial contribution and my subsequent rewriting and
redesigning.
