evolve: move builddependencies() and _singlesuccessor() to utility module
The builddependencies() and _singlesuccessor() function are very useful
functions and can be used at a lot of places. They are also used in topic
extension also, so let's move them to utility. However moving them to utility
won't help anything in the topic extension.
====================================
Testing head checking code: Case A-5
====================================
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 A: simple case involving a branch being superceeded by another.
TestCase 5: New changeset as parent of the successor
.. old-state:
..
.. * 1-changeset branch
..
.. new-state:

.. * 2rchangeset branch, head is a successor, but other is new
