rebase: filter out descendants of divergence-causing commits earlier
`hg rebase` treats obsolete commits differently depending what has
happened to the commit:
1) Obsolete commit without non-obsolete successors: Skipped, and a
note is printed ("it has no successor").
2) Obsolete commit with a successor in the destination (ancestor of
it): Skipped, and a note is printed ("already in destination").
3) Obsolete commit with a successor in the rebase set: The commit and
its descendants are skipped, and a note is printed ("not rebasing
<commit> and its descendants as this would cause divergence"), unless
`allowdivergence` config set.
4) Obsolete commit with a successor elsewhere: Error ("this rebase
will cause divergences"), unless `allowdivergence` config set.
Before this patch, we did all those checks up front, except for (3),
which was checked later. The later check consisted of two parts: 1)
filtering out of descendants, and 2) conditionally printing message if
the `allowdivergence` config was not set. This patch makes it so we do
the filtering early.
A consequence of filtering out divergence-causing commits earlier is
that we rebase commits in slightly different order, which has some
impact on tests.

==================================== Testing head checking code: Case D-2 ==================================== Mercurial checks for the introduction of new heads on push. Evolution comes into play to detect if existing branches on the server are being replaced by some of the new one we push. This case is part of a series of tests checking this behavior. Category D: remote head is "obs-affected" locally, but result is not part of the push TestCase 1: remote branch has 2 changes, head is pruned, other is rewritten but result is not pushed .. old-state: .. .. * 1 changeset branch .. .. new-state: .. .. * old head is pruned .. * 1 new branch succeeding to the other changeset in the old branch .. * 1 new unrelated branch .. .. expected-result: .. .. * push allowed .. * pushing only the unrelated branch: denied .. .. graph-summary: .. ..
