This is to support efficient chunk diff. Most of the churn in this patch
comes from updating test expectations, and updating every Ref construction
to include a height and every MetaTuple to include a Ref.
A novel chunk may contain references to any other novel chunk, as long
as there are no cycles. This means that breaking up the stream of
novel chunks being written to the server into batches risks creating
races -- chunks in one batch might reference chunks in another,
meaning that the server would somehow need to be able to
cross-reference batches. This seems super hard, so we've just forced
the code to write in one massive batch upon Commit(). We'll evaluate
the performance of this solution and see what we need to change.
Also, there's a terrible hack in HandleWriteValue to make it so that
pulls can work by back-channeling all their chunks via postRefs/ and
then writing the final Commit object via writeValue/
This can be fixed once we fix issue 822
