rewind: obsolete latest successors unless instructed otherwise
To prevent the creations of divergence, we automatically mark the successors set
of the rewinded changeset as obsoleted by the rewind result. A new flag
`--as-divergence` is added to disable this behavior.
This test file test the rewind command in several situations.
