mergecopies: add logic to process incomplete data
We first combine incomplete copies on the two sides of the topological CA
into complete copies.
Any leftover incomplete copies are then combined with the incomplete
divergences to reconstruct divergences spanning over the topological CA.
Finally we promote any divergences falsely flagged as incomplete to full
divergences.
Right now, there is nothing generating incomplete copy/divergence data,
so this code does nothing. Changes to _checkcopies to populate these
dicts are coming later in this series.
