stack: when stack base is obsolete, pick any successor, even if at random

There are situations when s0 is obsolete and we also cannot pick just one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

============================
Testing extensions isolation
============================

In this test case, we check that a repository using the extensions can co-exist
with a repository not using the extension.

  $ . $TESTDIR/testlib/common.sh

Setup
=====

Create repo

  $ hg init repo-evo
  $ cat > repo-evo/.hg/hgrc << EOF
  > [extensions]
  > evolve=
  > EOF
  $ hg init repo-topic
  $ cat > repo-topic/.hg/hgrc << EOF
  > [extensions]
  > topic=
  > EOF
  $ hg init repo-both
  $ cat > repo-both/.hg/hgrc << EOF
  > [extensions]
  > evolve=
  > topic=
  > EOF
  $ hg init repo-no-ext

check setup

  $ hg -R repo-evo  help -e evolve | head -n 1
  warning: --repository ignored
  evolve extension - extends Mercurial feature related to Changeset Evolution
  $ hg -R repo-both  help -e evolve | head -n 1
  warning: --repository ignored
  evolve extension - extends Mercurial feature related to Changeset Evolution
  $ hg -R repo-no-ext help -e evolve
  warning: --repository ignored
  abort: no such help topic: evolve
  (try 'hg help --keyword evolve')
  [10]
  $ hg -R repo-no-ext help -e topic
  warning: --repository ignored
  abort: no such help topic: topic
  (try 'hg help --keyword topic')
  [10]

start hgweb dir for all repo

  $ cat > hgweb.conf << EOF
  > [paths]
  > / = *
  > EOF

  $ hg serve -p $HGPORT -d --pid-file=hg.pid --web-conf hgweb.conf -A access.log -E error.log
  $ cat hg.pid >> $DAEMON_PIDS

Test isolation
--------------

As of 4.9 (and previous version). It seems like extensions are displayed as
enabled even for repository where they are not supposed to be. See the output
tagged `no-false`.

(however, topic and evolve are not supposed to affect other repository as shown
in the rest of this test).

  $ get-with-headers.py $LOCALIP:$HGPORT 'repo-no-ext/help/extensions' | grep 'enabled extensions' -A 7

  $ get-with-headers.py $LOCALIP:$HGPORT 'repo-evo/help/extensions' | grep 'enabled extensions' -A 7
  enabled extensions:

  $ get-with-headers.py $LOCALIP:$HGPORT 'repo-both/help/extensions' | grep 'enabled extensions' -A 9
  enabled extensions:

  <dl>
   <dt>evolve
   <dd>extends Mercurial feature related to Changeset Evolution

  </dl>
  <p>
  disabled extensions:
  $ get-with-headers.py $LOCALIP:$HGPORT 'repo-no-ext/help/extensions' | grep 'enabled extensions' -A 9
  enabled extensions: (no-false !)
  </p> (no-false !)
  <dl> (no-false !)
   <dt>evolve (no-false !)
   <dd>extends Mercurial feature related to Changeset Evolution (no-false !)
   <dt>topic (no-false !)
   <dd>support for topic branches (no-false !)
  </dl> (no-false !)
  <p> (no-false !)
  disabled extensions: (no-false !)

make sure repos don't affect each other (and check both ways)
