evolve: make sure divergence resolution doesn't undo changes (issue6203)
Before this patch, in content-divergence resolution logic if resolution
parent is not the parent of any of the two divergent changesets then
it could undo some changes introduced by previous revs (while resolving
stack of content-divergent changesets) as demonstrated by the test added in
previous patch.
To solve this, what this patch doing is: if divergent cset has obsolete
parent with a successor then first resolve the "orphan" instability of
divergent cset by relocating, then perform the content-divergence resolution.
After this change in logic, I found that it's kind of more correct as
reflected by the changes in tests/test-evolve-content-divergent-corner-cases.t
where it prevented creating conflicts while merging.
Changes in tests/test-evolve-content-divergent-stack.t demonstrate the fixed
behaviour.
Next patches will be covering the `evolve --continue` case for the relocation
of "divergent" cset.
This test file test the various messages when accessing obsolete
revisions.
