topic: use distinct names for distinct origvalidator and _validate()

Here, the same topicrepo.transaction method, we set up various transaction
validators. On older hg versions (5.3 and older) this involves storing the
original transaction validator (i.e. tr._validator function) and creating a
wrapper function to use as the replacement.

In cases when multiple
topic-related validators were needed, the code used to store tr._validator
multiple times, and create a wrapper function that used origvalidator multiple
times as well. In such cases we can no longer use the same names for the
functions/variables, as they are used inside multiple validator functions, but
are going to be overridden by later assignments/definitions (due to the shared
names), since it's done in the scope of the same topicrepo.transaction().

Names can be better, but it'll do for now, and at some point we'll simply drop
compatibility for 5.3, which should happen relatively soon.

====================================
Testing head checking code: Case D-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 D: remote head is "obs-affected" locally, but result is not part of the push
TestCase 1: remote branch has 2 changes, head is pruned, other is rewritten but result is not pushed

.. old-state:
..
.. * 1 changeset branch
..
.. new-state:
..
.. * old head is pruned
.. * 1 new branch succeeding to the other changeset in the old branch
.. * 1 new unrelated branch
..
.. expected-result:
..
.. * push allowed
.. * pushing only the unrelated branch: denied
