stack: when stack base is obsolete, pick any successor, even if at random

There are situations when s0 is obsolete and we also cannot pick just one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

Test NGTip feature
==================

Simple linear case

  $ echo babar >> jungle
  $ hg add jungle
  $ hg ci -t elephant -m babar
  active topic 'elephant' grew its first changeset
  (see 'hg help topics' for more information)

  $ hg log -G
  @  4 (elephant) babar
  |
  o  3 () c_delta
  |
  o  2 () c_gamma
  |
  o  1 () c_beta
  |
  o  0 () c_alpha
  
  $ hg log -G -r 'ngtip(.)'
  o  3 () c_delta
  |
  ~
  $ hg log -r 'default'
  3 () c_delta


multiple heads with topic

  $ hg up "desc('c_beta')"
  0 files updated, 0 files merged, 3 files removed, 0 files unresolved
  $ echo zephir >> jungle
  $ hg add jungle
  $ hg ci -t monkey -m zephir
  active topic 'monkey' grew its first changeset
  (see 'hg help topics' for more information)
  $ hg log -G
  @  5 (monkey) zephir
  |
  | o  4 (elephant) babar
  | |
  | o  3 () c_delta

  |
  o  0 () c_alpha
  
  $ hg log -r 'ngtip(.)'
  3 () c_delta
  $ hg log -r 'default'
  3 () c_delta

one of the head is a valid tip

  $ hg up "desc('c_delta')"
  2 files updated, 0 files merged, 1 files removed, 0 files unresolved
  $ echo epsilon >> epsilon
  $ hg add epsilon
  $ hg ci -m "c_epsilon"
  $ hg log -G

Default destination for histedit
================================

By default histedit should edit changesets with the current topic only
(even when based on other draft changesets)

  $ hg phase 'desc(c_zeta)'

  pick 38eea8439aee 14 arthur
  pick 411315c48bdc 15 pompadour
  #  p, pick = use commit

  $ cd ..

destination check: when active topic is empty

  $ hg init emptytopic
  $ cd emptytopic
  $ echo a > a
  $ hg ci -Am "added a"
  adding a
  $ hg topic foo
  marked working directory as topic: foo
  $ hg up
  clearing empty topic "foo"
  0 files updated, 0 files merged, 0 files removed, 0 files unresolved

destination check: when wdp has a topic but wdir has no active topic:

  $ hg topic foo
  marked working directory as topic: foo
  $ echo b > b
  $ hg ci -Am "added b"
  adding b
  active topic 'foo' grew its first changeset
  (see 'hg help topics' for more information)
  $ hg topic --clear
  $ hg up
