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.

Orphan changeset and trying to relocate a node on top of itself (issue6097)
https://bz.mercurial-scm.org/show_bug.cgi?id=6097

  $ . $TESTDIR/testlib/common.sh

  $ cat << EOF >> $HGRCPATH
  > [extensions]
  > rebase =
  > evolve =
  > EOF

  $ hg init issue6097
  $ cd issue6097

  $ echo apricot > a
  $ hg ci -qAm apricot

  $ echo banana > b
  $ hg ci -qAm banana

Let's go back to amend 0 and make an orphan out of 1

  $ hg up -q 0
  $ echo coconut > c
  $ hg add -q c
  $ hg ci --amend -m 'apricot and coconut'
  1 new orphan changesets

Now rebase the successor of 0 on top of 1

  $ hg rebase -r . -d 1
  rebasing 2:32acf8fb1b23 tip "apricot and coconut"
  1 new orphan changesets

Pruning 1 just to get it out of the way

  $ hg prune -q 1

Note how both the regular DAG and the obsolescence graph are linear, but the
paths from 3 to 0 are different: 3-1-0 and 3-2-0
