stablerange: move the slicing method on the central class

We migrate code away for the individual range class.

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

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 A: checking simple case invoving a branch being superceeded by another.
TestCase 2: multi-changeset branch

.. old-state:
