uncommit: move _movedirstate() to scmutil for reuse

The function should be applicable generically when moving from one
commit to another. I'll try to add more callers when I find time.

I'm not convinced it's handling all the cases correctly, but we should
have a generic function for this kind of operation, so I think it
belongs somewhere in core (not in the uncommit extension).

====================================
Testing head checking code: Case B-2
====================================

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 2: multi-changeset branch, head is pruned, rest is superceeded, through other

.. old-state:
..
.. * 2 changeset branch
..
.. new-state:
..
.. * old head is rewritten then pruned
.. * 1 new branch succeeding to the other changeset in the old branch (through another obsolete branch)
..
.. expected-result:
..
.. * push allowed
