stack: add a very first version of stack display with 'hg topic --list'

This mark the first step toward a set of feature dedicated to displaying and
moving within the current stack of work. Everything is still super basic so
don't look too much at the feature.

The goals of this changeset are:
* having a flag to trigger the feature
* having a basic (imperfect selection mechanism)

  $ . "$TESTDIR/testlib"

Initial setup


  $ cat << EOF >> $HGRCPATH
  > [ui]
  > logtemplate = {rev} {branch} \{{get(namespaces, "topics")}} {phase} {desc|firstline}\n
  > EOF

(new head warning seems buggy)
  $ hg init main
  $ cd main
  $ echo aaa > aaa
  $ hg add aaa
  $ hg commit -m c_a
  $ echo aaa > bbb
  $ hg add bbb
  $ hg commit -m c_b
  $ hg topic foo
  $ echo aaa > ccc
  $ hg add ccc
  $ hg commit -m c_c
  $ echo aaa > ddd
  $ hg add ddd
  $ hg commit -m c_d
  created new head
  $ echo aaa > eee
  $ hg add eee
  $ hg commit -m c_e
  created new head
  $ echo aaa > fff
  $ hg add fff
  $ hg commit -m c_f
  created new head
  $ hg log -G
  @  5 default {foo} draft c_f

  o  4 default {foo} draft c_e

  o  3 default {foo} draft c_d

  o  2 default {foo} draft c_c

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
