evolve: update the public divergence resolution logic to cover --continue case
To continue the interrupted evolve in case of public divergence:
we will have to store the node of that public cset which was in
content divergence with the other cset, so that we can perform the
phase divergence resolution between that public cset and a newnode
which is the result of content-divergence resolution.
Added tests reflect the behaviour this patch adds.
====================================
Testing head checking code: Case D-7
====================================
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 7: single changesets, superseeded multiple time then pruned (on a new changeset unpushed) changeset
This is a partial push variation of B6
.. old-state:
..
.. * 1 changeset branch
..
.. new-state:
..
.. * old branch is rewritten onto another one,
.. * The rewriting it again rewritten on the root
.. * the new version is then pruned.

.. * push allowed
