stack: when stack base is obsolete, pick any successor, even if at random

There are situations when s0 is obsolete and we also cannot pick just one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.

New clones shouldn't have topics in any on-disk caches (issue6841)

  $ echo foo > foo
  $ hg topic topic-foo
  marked working directory as topic: topic-foo
  $ hg ci -qAm foo

  $ cd ..

cloning via ssh to use wire protocol

  $ hg clone ssh://user@dummy/orig new-clone -q
  $ cd new-clone

on-disk caches are using bare branch names only

  $ f -Hq .hg/cache/rbc-names-v?
  0000: 64 65 66 61 75 6c 74                            |default|
  $ grep topic-foo .hg/cache/*
  [1]

and pushing works fine

  $ hg push ssh://user@dummy/publishing
  pushing to ssh://user@dummy/publishing
