topics: add t0 and b0 to the stack

t0 or b0 will be the base of the stack and it's the parent of t1 or b1. The cool
thing about this is that if you update to t0 using `hg up t0` or do `hg prev` on
t1, you will be updated to t0 with the current topic preserved.

This patch adds t0 to stack and implement the preserving topic case for t0 while
using `hg update`.

  $ hg init main
  $ cd main
  $ hg branch other
  marked working directory as branch other
  (branches are permanent and global, did you want a bookmark?)
  $ echo aaa > aaa
  $ hg add aaa
  $ hg commit -m c_a
  $ echo aaa > bbb
  $ hg add bbb
  $ hg commit -m c_b
  $ hg branch foo

  $ hg commit -m c_c
  $ echo aaa > ddd
  $ hg add ddd
  $ hg commit -m c_d
  $ echo aaa > eee
  $ hg add eee
  $ hg commit -m c_e
  $ echo aaa > fff
  $ hg add fff
  $ hg commit -m c_f
  $ hg log -G

Check that topic without any parent does not crash --list
---------------------------------------------------------

  $ hg up other
  0 files updated, 0 files merged, 4 files removed, 0 files unresolved
  $ hg stack
  ### branch: other
  b2@ c_b (current)
  b1: c_a
  $ hg phase --public 'branch("other")'
  $ hg up foo
  4 files updated, 0 files merged, 0 files removed, 0 files unresolved

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

'hg stack' list all changeset in the topic

  $ hg branch
  foo
  $ hg stack
  ### branch: foo
  b4@ c_f (current)
  b3: c_e
  b2: c_d
  b1: c_c
  b0^ c_b (base)

Test "t#" reference
-------------------

  $ hg up b2
  0 files updated, 0 files merged, 2 files removed, 0 files unresolved
  $ hg up foo
  2 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ hg up b42
  abort: cannot resolve "b42": branch "foo" has only 4 changesets
  [255]
  $ hg up b2
  0 files updated, 0 files merged, 2 files removed, 0 files unresolved
  $ hg summary

   c_d
  branch: foo
  commit: (clean)
  update: 2 new changesets (update)
  phases: 4 draft

Case with some of the branch unstable
------------------------------------

  $ echo bbb > ddd
  $ hg commit --amend
  $ hg log -G
  @  7 foo {} draft c_d
  |
  | o  5 foo {} draft c_f
  | |
  | o  4 foo {} draft c_e

  | x  3 foo {} draft c_d
  |/
  o  2 foo {} draft c_c
  |
  o  1 other {} public c_b
  |
  o  0 other {} public c_a
  
  $ hg stack
  ### branch: foo
  b4$ c_f (unstable)
  b3$ c_e (unstable)
  b2@ c_d (current)
  b1: c_c
  b0^ c_b (base)
  $ hg up b3

  $ hg stack
  ### branch: foo
  b4$ c_f (unstable)
  b3$ c_e (current unstable)
  b2: c_d
  b1: c_c
  b0^ c_b (base)
  $ hg up b2
  1 files updated, 0 files merged, 1 files removed, 0 files unresolved

Also test the revset:

  $ hg log -r 'stack()'
  2 foo {} draft c_c
  7 foo {} draft c_d
  4 foo {} draft c_e
  5 foo {} draft c_f

Case with multiple heads on the topic
-------------------------------------

Make things linear again

  $ hg rebase -s 'desc(c_e)' -d 'desc(c_d) - obsolete()'
  rebasing 4:4f2a69f6d380 "c_e"
  rebasing 5:913c298d8b0a "c_f"
  $ hg log -G
  o  9 foo {} draft c_f
  |
  o  8 foo {} draft c_e
  |
  @  7 foo {} draft c_d
  |
  o  2 foo {} draft c_c
  |
  o  1 other {} public c_b
  |
  o  0 other {} public c_a
  

Create the second branch

  $ hg up 'desc(c_d)'
  0 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ echo aaa > ggg
  $ hg add ggg
  $ hg commit -m c_g
  created new head
  $ echo aaa > hhh
  $ hg add hhh
  $ hg commit -m c_h
  $ hg log -G
  @  11 foo {} draft c_h
  |
  o  10 foo {} draft c_g
  |
  | o  9 foo {} draft c_f
  | |
  | o  8 foo {} draft c_e
  |/
  o  7 foo {} draft c_d
  |
  o  2 foo {} draft c_c
  |
  o  1 other {} public c_b
  |
  o  0 other {} public c_a
  

Test output

  $ hg stack
