stack: when stack base is obsolete, pick any successor, even if at random

There are situations when s0 is obsolete and we also cannot pick just one
successor for it to use in stack. In such a case, let's pick the "latest"
successor from the first set.

We're assuming that obsutil.successorssets() returns data in the same order (it
should, since it makes sure to sort data internally). Keeping that in mind,
while the successor picked for s0 by this code is not based on any sort of
sophisticated logic, it should nonetheless be the same every time.

This patch is probably not going to completely break anything that was
previously working fine, because the previous behavior was to just abort with
an exception.

Checking affected topic namespaces before history rewrites
==========================================================

  $ . "$TESTDIR/testlib/common.sh"

  $ cat >> $HGRCPATH << EOF
  > [extensions]
  > evolve =
  > topic =
  > rebase =
  > histedit =
  > [phases]
  > publish = no
  > [experimental]
  > tns-allow-rewrite =
  > EOF

  $ hg init repo
  $ cd repo

Make sure general checks in precheck() happen before topic namespaces checks

  $ hg prune null
  abort: cannot prune the null revision
  (no changeset checked out)
  [10]

  $ echo apple > a
  $ hg ci -qAm apple

  $ hg debug-topic-namespace foo
  marked working directory as topic namespace: foo
  $ hg topic bar
  marked working directory as topic: bar
  $ echo banana > b
  $ hg ci -qAm 'banana'

Allowing topic namespaces with --config works correctly

  $ echo broccoli > b
  $ hg amend -m 'broccoli'
  abort: refusing to amend changesets with these topic namespaces: foo
  (modify experimental.tns-allow-rewrite to allow rewriting changesets from these topic namespaces)
  [10]
  $ hg amend -m 'broccoli' --config experimental.tns-allow-rewrite=foo,something-unrelated

  $ echo coconut > b
  $ hg ci -qAm 'coconut'
