copies: split the combination of the copies mapping in its own function

In some case, this part take up to 95% of the copy tracing that take about a
hundred second. This poor performance comes from the fact we keep duplciating
and merging dictionary that are mostly similar.

I want to experiment with smarter native code to do this, so I need to isolate
the function first.

====================================
Testing head checking code: Case A-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 A: simple case involving a branch being superceeded by another.
TestCase 2: multi-changeset branch

.. old-state:
..
.. * 1 branch with 2 changesets
..
.. new-state:
..
.. * another 2-changeset branch succeeding the old one
..
.. expected-result:
..
.. * push allowed
