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 NGTip feature
==================

Simple linear case

  $ echo babar >> jungle
  $ hg add jungle
  $ hg ci -t elephant -m babar
  active topic 'elephant' grew its first changeset

  $ hg log -G
  @  4 (elephant) babar
  |
  o  3 () c_delta
  |
  o  2 () c_gamma
  |
  o  1 () c_beta
  |
  o  0 () c_alpha
  
  $ hg log -r 'ngtip(.)'
  3 () c_delta
  $ hg log -r 'default'
  3 () c_delta


multiple heads with topic

  $ hg up "desc('c_beta')"
  0 files updated, 0 files merged, 3 files removed, 0 files unresolved
  $ echo zephir >> jungle
  $ hg add jungle
  $ hg ci -t monkey -m zephir
  active topic 'monkey' grew its first changeset
  $ hg log -G
  @  5 (monkey) zephir
  |
  | o  4 (elephant) babar
  | |
  | o  3 () c_delta
  | |
  | o  2 () c_gamma
  |/
  o  1 () c_beta
  |
  o  0 () c_alpha
  
  $ hg log -r 'ngtip(.)'
  3 () c_delta
  $ hg log -r 'default'
  3 () c_delta

one of the head is a valid tip

  $ hg up "desc('c_delta')"
  2 files updated, 0 files merged, 1 files removed, 0 files unresolved
  $ echo epsilon >> epsilon
  $ hg add epsilon
  $ hg ci -m "c_epsilon"
  $ hg log -G
  @  6 () c_epsilon
