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.

Testing the config option for rejecting draft changeset without topic
The config option is "experimental.topic-mode.server"

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

Creating a server repo

  $ hg init server
  $ cd server
  $ cat <<EOF >>.hg/hgrc
  > [phases]
  > publish=False
  > [experimental]
  > topic-mode.server = enforce
  > EOF

  $ hg topic server
  marked working directory as topic: server
  $ for ch in a b c; do echo foo > $ch; hg ci -Aqm "Added "$ch; done
  $ hg ph -p 0

  $ hg log -G -T "{rev}:{node|short}\n{desc}  {topics}"
  @  2:a7b96f87a214
  |  Added c  server
  o  1:d6a8197e192a
  |  Added b  server
  o  0:49a3f206c9ae
     Added a

  $ cd ..

Creating a client repo

  $ hg clone server client
  updating to branch default
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ cd client
  $ hg up server
  switching to topic server
  2 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ hg log -G -T "{rev}:{node|short}\n{desc}  {topics}"
  @  2:a7b96f87a214
  |  Added c  server
  o  1:d6a8197e192a
  |  Added b  server
  o  0:49a3f206c9ae
     Added a

  $ hg topic
   * server (2 changesets)

Create a changeset without topic

  $ hg topic --clear
  $ echo foo > d
  $ hg ci -Aqm "added d"

  $ hg log -G -T "{rev}:{node|short}\n{desc}  {topics}"
  @  3:4e8b0e0237c6
  |  added d
  o  2:a7b96f87a214
  |  Added c  server
  o  1:d6a8197e192a
  |  Added b  server
  o  0:49a3f206c9ae
     Added a

Push a draft changeset without topic

  $ hg push ../server  --new-branch
  pushing to ../server
  searching for changes
  adding changesets
  adding manifests
  adding file changes
  added 1 changesets with 1 changes to 1 files
  transaction abort!
  rollback completed
  abort: rejecting draft changesets: 4e8b0e0237
  [255]

  $ hg push ../server -f
  pushing to ../server
  searching for changes
  adding changesets
  adding manifests
  adding file changes
  added 1 changesets with 1 changes to 1 files
  transaction abort!

Grow the stack with more changesets having topic

  $ hg topic client
  marked working directory as topic: client
  $ for ch in e f g; do echo foo > $ch; hg ci -Aqm "Added "$ch; done;

  $ hg log -G -T "{rev}:{node|short}\n{desc}  {topics}"
  @  6:42c4ac86452a
  |  Added g  client
  o  5:3dc456efb491
  |  Added f  client
  o  4:18a516babc60
  |  Added e  client
  o  3:4e8b0e0237c6
  |  added d
  o  2:a7b96f87a214
  |  Added c  server
  o  1:d6a8197e192a
  |  Added b  server
  o  0:49a3f206c9ae
     Added a

Pushing multiple changeset with some having topics and some not

  $ hg push ../server --new-branch
  pushing to ../server
  searching for changes
  adding changesets
  adding manifests
  adding file changes
  added 4 changesets with 4 changes to 4 files
  transaction abort!
  rollback completed
  abort: rejecting draft changesets: 4e8b0e0237
  [255]

Testing case when both experimental.topic-mode.server and
experimental.topic.publish-bare-branch are set

  $ cd ../server
  $ echo 'topic.publish-bare-branch=True' >> .hg/hgrc
  $ cd ../client
  $ hg push ../server --new-branch
  pushing to ../server
  searching for changes
  adding changesets
  adding manifests
  adding file changes
  added 4 changesets with 4 changes to 4 files
  transaction abort!
  rollback completed
  abort: rejecting draft changesets: 4e8b0e0237
  [255]

Turning the changeset public and testing push

  $ hg phase -r 3 -p
  $ hg log -G -T "{rev}:{node|short}\n{desc}  {topics}"
  @  6:42c4ac86452a
  |  Added g  client
  o  5:3dc456efb491
  |  Added f  client
  o  4:18a516babc60
  |  Added e  client
  o  3:4e8b0e0237c6
  |  added d
  o  2:a7b96f87a214
  |  Added c
  o  1:d6a8197e192a
  |  Added b
  o  0:49a3f206c9ae
     Added a

  $ hg push ../server
  pushing to ../server
  searching for changes
  adding changesets
  adding manifests
  adding file changes
  added 4 changesets with 4 changes to 4 files
  active topic 'server' is now empty
