evolve: handle stabilization of merge changeset with both parents obsoleted

This patch adds logic to stabilize an orphan merge changeset having both parents
obsoleted.

The logic tries to first stabilize the merge changeset on successor of second
parent and then stabilize the new changeset formed on the successor of first
parent. We are stabilizing on second parent first and then to second parent to
preserve the first parent's successor as first parent of the merge changeset.

Conflicts can occcur and we can loose processing information, therefore we store
a variable in statefile `orphanmerge` which represents whether we are processing
a merge changeset with both parents obsoleted.

Thanks to Pierre-Yves David for suggesting this way and helping to understand
the correctness of this.

More rigourous test cases for this will be added in next patch.

==================================================
Test for `hg debugconvertbookmark` added by topics
==================================================

  $ . "$TESTDIR/testlib/topic_setup.sh"

Setting up the things

  $ echo "Fix 1" > l
  $ hg commit -Aqm "Fixing first"
  $ echo "Fix 2" > m
  $ hg commit -Aqm "Fixing second"

Generic tests
=============

Help for the command
--------------------

  $ hg help debugconvertbookmark
  hg debugcb [-b BOOKMARK] [--all]
  
  aliases: debugconvertbookmark
  
  Converts a bookmark to a topic with the same name.
  
  options:
  
   -b --bookmark VALUE bookmark to convert to topic
      --all            convert all bookmarks to topics
  
  (some details hidden, use --verbose to show complete help)

Running without any argument
----------------------------

  $ hg debugconvertbookmark
  abort: you must specify either '--all' or '-b'

Changing a particular bookmark to topic
=======================================

  $ hg debugconvertbookmark -b hellos
  changed topic to "hellos" on 2 revisions
  $ hg log -G
  o  [6:98ae7930f6ed] Second commit
  |    topic: hellos
  o  [5:ff69f6ee4618] First commit
  |    topic: hellos
  | @  [4:ec0e17135a94] Fixing second

  |/
  o  [0:249055fcca50] root
  

Changing all bookmarks to topic
===============================

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

  $ hg debugconvertbookmark --all
  switching to topic secondfix
  changed topic to "secondfix" on 2 revisions
  $ hg log -G
  @  [8:5f0f9cc1979a] Fixing second

Trying with multiple bookmarks on a single changeset
----------------------------------------------------

  $ echo "multiple bookmarks" >> m
  $ hg commit -Aqm "Trying multiple bookmarks"
  $ hg bookmark book1

Check that phase are properly take in account
---------------------------------------------

(we reuse above test, taking advantage of a small bug regarding stacked bookmarks. we can fuse the two tests once that bug is fixed)
