rewind: walk obsmarkers and add more targets to rewind to

We're trying to save users from accidentally losing any content changes if they
try to rewind to e.g. only one component of a fold. In such case we're also
adding the rest of the components.

Testing `hg stack` on complex cases when we have multiple successors because of
divergence, split etc.
