rewind: add a --dry-run flag

There are 3 cases handled separately in formatstatus():

- common-case rewind when we have X current successors rewinding to Y
  predecessors

- rewinding with --as-divergence, when we don't obsolete current successors

- rewinding pruned commits, when we don't have current successors to show

In the common case, we might have sub-cases that change the output with
--dry-run (but not the way the rewind operates):

- more predecessors than successors (e.g. after a fold), in which case we
  simply use successorsmap, which maps successors to a set of predecessors

- equal number of predecessors and successors, see the previous case

- more successors than predecessors (e.g. after a split), in which case we
  use a reverse of successorsmap (rsm), which maps predecessors to a set of
  successors and exists only for the sake of --dry-run functionality

These two dicts allow us to group rewind targets and output separate lines for
separate predecessors<->successors relations.
