topic: use distinct names for distinct origvalidator and _validate()

Here, the same topicrepo.transaction method, we set up various transaction
validators. On older hg versions (5.3 and older) this involves storing the
original transaction validator (i.e. tr._validator function) and creating a
wrapper function to use as the replacement.

In cases when multiple
topic-related validators were needed, the code used to store tr._validator
multiple times, and create a wrapper function that used origvalidator multiple
times as well. In such cases we can no longer use the same names for the
functions/variables, as they are used inside multiple validator functions, but
are going to be overridden by later assignments/definitions (due to the shared
names), since it's done in the scope of the same topicrepo.transaction().

Names can be better, but it'll do for now, and at some point we'll simply drop
compatibility for 5.3, which should happen relatively soon.

  $ hg init main

  $ hg branch double//slash

Commit extras have branch name without formatting
-------------------------------------------------

  $ hg log -r 1 -T '{rev}: {join(extras, " ")}\n'
  1: branch=double//slash
  $ hg log -r 5 -T '{rev}: {join(extras, " ")}\n'
  5: branch=foo//bar

Check that branch without any parent does not crash stack
---------------------------------------------------------

  $ hg up double//slash//
  0 files updated, 0 files merged, 4 files removed, 0 files unresolved
  $ hg stack
  ### target: double//slash (branch)
  s2@ c_b (current)
  s1: c_a
  $ hg phase --public 'branch("double//slash//")'
  $ hg up foo//bar//
  4 files updated, 0 files merged, 0 files removed, 0 files unresolved

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

'hg stack' lists all changeset on the branch

  $ hg branch
  foo//bar
  $ hg stack
  ### target: foo//bar (branch)
  s4@ c_f (current)
  s3: c_e
  s2: c_d
  s1: c_c
  s0^ c_b (base)
  $ hg stack -v
  ### target: foo//bar (branch)
  s4(18b3ff044de9)@ c_f (current)
  s3(b1913e064ca1): c_e
  s2(8fad7e98adf6): c_d
  s1(da14ac95d156): c_c
  s0(2450a061c0f0)^ c_b (base)

Test "s#" reference
-------------------

  $ hg up s2

  $ hg up foo//bar//
  2 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ hg up s42
  abort: cannot resolve "s42": branch "foo//bar//" has only 4 non-public changesets

  $ hg summary

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

  $ echo bbb > ddd
  $ hg commit --amend
  2 new orphan changesets
  $ hg log -G
  @  6 foo//bar {} draft c_d

  $ hg stack
  ### target: foo//bar (branch)
  s4$ c_f (orphan)
  s3$ c_e (orphan)

  $ hg up s3

  s2: c_d
  s1: c_c
  s0^ c_b (base)
  $ hg up s2
  1 files updated, 0 files merged, 1 files removed, 0 files unresolved

Also test the revset:

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

Case with multiple heads on the branch
--------------------------------------

Make things linear again

  $ hg rebase -s 'desc(c_e)' -d 'desc(c_d) - obsolete()'
  rebasing 4:b1913e064ca1 "c_e"
  rebasing 5:18b3ff044de9 "c_f"
  $ hg log -G
  o  8 foo//bar {} draft c_f
  |
  o  7 foo//bar {} draft c_e
  |
  @  6 foo//bar {} draft c_d
  |
  o  2 foo//bar {} draft c_c
  |
  o  1 double//slash {} public c_b
  |
  o  0 double//slash {} public c_a
  

Create the second head

  $ 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
  (consider using topic for lightweight branches. See 'hg help topic')
  $ echo aaa > hhh
  $ hg add hhh
  $ hg commit -m c_h
  $ hg log -G
  @  10 foo//bar {} draft c_h
  |
  o  9 foo//bar {} draft c_g
  |
  | o  8 foo//bar {} draft c_f
  | |
  | o  7 foo//bar {} draft c_e
  |/
  o  6 foo//bar {} draft c_d
  |
  o  2 foo//bar {} draft c_c
  |
  o  1 double//slash {} public c_b
  |
  o  0 double//slash {} public c_a
