stack: fix printing order in case of unstability

The stack was displayed using revision number order, this give good result in
the simple case (straight stack) but give bad result when the stack is not
linear because of unstability.

We fixes it by reusing the evolution logic for sorting. As we do not live next
to evolution yet, we duplicated this logic for now.

Initial setup

(new head warning seems buggy)
  $ hg init main
  $ cd main
  $ echo aaa > aaa
  $ hg add aaa

  $ echo aaa > bbb
  $ hg add bbb
  $ hg commit -m c_b

Simple test
-----------

hg topic -l list all changeset in the topic

  $ hg topic
   * foo
  $ hg topic --list
  c_c
  c_d
  c_e
  c_f

error case, nothing to list

  $ hg topic --clear
  $ hg topic --list
  abort: no active topic to list
  [255]

Case with some of the topic unstable
------------------------------------

  $ hg up 'desc(c_d)'
  switching to topic foo
  0 files updated, 0 files merged, 2 files removed, 0 files unresolved
  $ echo bbb > ddd
  $ hg commit --amend
  $ hg log -G
