evolve: add test for the case where public divergence on difference parents

This test make sure that public divergence resolution also handle the case when
divergentes changeset does not share the same parent at one end because one end
simply rebase. The other side has actual an actual diff change.

For now this would work only for the case when we need to relocate
the mutable one. Other case is still left to work on.

Test for handling of content divergence with public cset using `hg evolve`
==========================================================================

Setup
=====
  $ cat >> $HGRCPATH <<EOF
  > [alias]
  > glog = log -GT "{rev}:{node|short} {desc|firstline}\n {phase} {troubles}\n\n"
  > [phases]
  > publish = False
  > [extensions]
  > rebase =
  > EOF
  $ echo "evolve=$(echo $(dirname $TESTDIR))/hgext3rd/evolve/" >> $HGRCPATH

Testing the case when both divergent cset are on the same parent and no-conflict in merging:
-------------------------------------------------------------------------------------

Prepare the repository:

  $ hg init pubdiv
  $ cd pubdiv
  $ for ch in a b; do
  >   echo $ch > $ch;
  >   hg ci -Aqm "added "$ch;
  > done;
  $ hg glog
  @  1:5f6d8a4bf34a added b
  |   draft
  |
  o  0:9092f1db7931 added a
      draft
  

Make an amend and change phase to public:

  $ sed -i "1 i I am first" b
  $ hg amend
  $ hg phase --public

Amend again to create a cset divergent to public one:

  $ hg up 1 --hidden -q
  updated to hidden changeset 5f6d8a4bf34a
  (hidden revision '5f6d8a4bf34a' was rewritten as: 44f360db368f)
  working directory parent is obsolete! (5f6d8a4bf34a)

  $ echo "I am second" >> b
  $ hg ci --amend -m "updated b"
  1 new content-divergent changesets

  $ hg glog
  @  3:dcdaf152280a updated b
  |   draft content-divergent

  | o  2:44f360db368f added b
  |/    public
  |
  o  0:9092f1db7931 added a
      public
  

Lets resolve the public content-divergence:

  $ hg evolve --content-divergent
  merge:[3] updated b
  with: [2] added b
  base: [1] added b
  merging "other" content-divergent changeset '44f360db368f'
  merging b
  0 files updated, 1 files merged, 0 files removed, 0 files unresolved
  computing new diff

  working directory is now at c1aa9cfb6cf8

Following graph log shows that it correctly merged the two divergent csets:

Testing the case when divergence is not created by actual diff change, but because of rebasing:
------------------------------------------------------------------------------------------------

Prepare the repo:

  $ cd ..
  $ hg init rebasediv
  $ cd rebasediv
  $ for ch in a b c; do
  >   echo $ch > $ch;

  o  1:5f6d8a4bf34a added b
  |   draft
  |
  o  0:9092f1db7931 added a
      draft
  

On server side: a new cset is added based on rev 1 and rev 2 is rebased on newly added cset:

  $ hg up .^ -q
  $ echo d > d
  $ hg ci -Am "added d"
  adding d
  created new head

  $ hg rebase -r 2 -d .
  rebasing 2:155349b645be "added c"

  $ hg glog

  o  1:5f6d8a4bf34a added b
  |   draft
  |
  o  0:9092f1db7931 added a
      draft
  

On user side: user has not pulled yet and amended the rev 2 which created the divergence after pull:
  $ hg up 2 --hidden -q
  updated to hidden changeset 155349b645be
  (hidden revision '155349b645be' was rewritten as: c0d7ee6604ea)
  working directory parent is obsolete! (155349b645be)

  $ echo cc >> c
  $ hg ci --amend -m "updated c"
  2 new content-divergent changesets

Lets change the phase to --public of branch which is pulled from server:
  $ hg phase --public -r 4
  $ hg glog -p
