obslog: also display patch for rebased changesets

This applies the same logic that is used for "merge-diff" to rebased
changesets. The successors' content is compared to the content of the
predecessors rebased in-memory on the new parents.

This highlights the changes that were actually introduced while rebasing (like
conflict resolution or API adjustment).

As a side effect, obslog now also outputs slightly more diffs for splits,
showing what parts of the original big changeset were moved to the smaller
split components (but for now it only works for the first few changesets).

====================================
Testing head checking code: Case C-1
====================================

Mercurial checks for the introduction of multiple heads on push. Evolution
comes into play to detect if existing heads on the server are being replaced by
some of the new heads we push.

This test file is part of a series of tests checking this behavior.

Category C: checking case were the branch is only partially obsoleted.
TestCase 1: 2 changeset branch, only the head is rewritten

.. old-state:
..
.. * 2 changeset branch
..
.. new-state:
..
.. * 1 new changesets branches superseding only the head of the old one
.. * base of the old branch is still alive
..
.. expected-result:
..
.. * push denied
