tests: add a test file of resolving orphaness of merge changesets

This patch adds a new test file named test-evolve-orphan-merge.t which contains
test cases when `hg evolve` try to stabilize a merge changeset which was orphan.

This file contains 20-30% of all the cases as we have got something to fix
before we add tests for rest of the cases. Going by this approach will make sure
we don't live unfixed cases in the test file and the test files does not become
a pile of hacks which are used to get in state when we fix the bugs.

====================================
Testing head checking code: Case B-6
====================================

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 B: simple case involving pruned changesets
TestCase 6: single changesets, pruned then superseeded (on a new changeset)

.. old-state:
..
.. * 1 changeset branch
..
.. new-state:
..
.. * old branch is rewritten onto another one,
.. * the new version is then pruned.

Actual testing
--------------

  $ hg push
  pushing to $TESTTMP/B6/server (glob)
  searching for changes
  adding changesets
  adding manifests
  adding file changes
  added 1 changesets with 1 changes to 1 files (+1 heads)
  2 new obsolescence markers
  obsoleted 1 changesets
