obshashrange: less brutal reset when receiving markers on existing node

We now target the affected ranges only. The implementation is still slow but
that should be better than what we had before.

Initial setup

  $ 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
  marked working directory as branch foo
  $ echo aaa > ccc
  $ hg add ccc
  $ 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
  ### target: other (branch)
  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
  ### target: foo (branch)
  b4@ c_f (current)
  b3: c_e
  b2: c_d
  b1: c_c
  b0^ c_b (base)
  $ hg stack -v
  ### target: foo (branch)
  b4(913c298d8b0a)@ c_f (current)
  b3(4f2a69f6d380): c_e
  b2(f61adbacd17a): c_d
  b1(3e9313bc4b71): c_c
  b0(4a04f1104a27)^ 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
  parent: 3:f61adbacd17a 
   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
  @  6 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
  ### target: foo (branch)
  b4$ c_f (unstable)
  b3$ c_e (unstable)
  b2@ c_d (current)
  b1: c_c
  b0^ c_b (base)
  $ hg up b3
  2 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ hg stack
  ### target: foo (branch)
  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
  6 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  8 foo {} draft c_f
  |
  o  7 foo {} draft c_e
  |
  @  6 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
  @  10 foo {} draft c_h
  |
  o  9 foo {} draft c_g
  |
  | o  8 foo {} draft c_f
  | |
  | o  7 foo {} draft c_e
  |/
  o  6 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
  ### target: foo (branch) (2 heads)
  b6@ c_h (current)
  b5: c_g
  b2^ c_d (base)
  b4: c_f

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

We amend the message to make sure the display base pick the right changeset

  $ hg up 'desc(c_d)'
  0 files updated, 0 files merged, 2 files removed, 0 files unresolved
  $ echo ccc > ddd
  $ hg commit --amend -m 'c_D'
