evolve: use merge.update() for resolving phase divergence
Iterating over the manifest when tree manifests and narrowness is in
play produces entries for paths outside the narrowspec that represent
trees. For example, if the tests/ directory of the hg repo was not in
the narrowspec (and the hg repo was using tree manifests, which it
doesn't), then there would be a "tests/" entry in the manifest. The
merge code deals with some of these cases. For example, it's valid to
do a merge if only the local side changes directories outside the
narrowspec. That allows rebasing a local commit onto a public commit
that had changes to the excluded paths to work.
However, _resolvephasedivergent() was iterating of the manifests,
which resulted in crashes for some of our users when they tried to
resolve phase-divergent commits (actually content-divergent commits
that became phase-divergent after the intermediate rebase). We can fix
that by relying on merge.update(), since that already handles this
case.
============================================
Testing obsolescence markers push: Cases D.4
============================================
Mercurial pushes obsolescences markers relevant to the "pushed-set", the set of
all changesets that requested to be "in sync" after the push (even if they are
already on both side).
This test belongs to a series of tests checking such set is properly computed
and applied. This does not tests "obsmarkers" discovery capabilities.
Category D: Partial Information Case
TestCase 4: Unknown changeset in between known changesets
D.4 Unknown changeset in between known one
==========================================
.. Mostly a clarification case

.. Should be treated as A.3 case:
