To make this easier to understand and harmonise the logic used in a
few places, I'm now planning to chop it up into a patch series,
probably something like this:

1. Change existing hash join code to use chunk-based accounting
2. Change existing hash join code to use a new interface for dealing
with batches
3. Add shared hash join support, single batch only
4. Add components for doing shared batch reading (unused)
5. Add multi-batch shared hash join support
