evolve: merge commit messages while resolving content-divergence (issue5877) While resolving content-divergence, there can be divergence in commit messages too which should be resolved. This patch uses the hg's internal merge API's to merge commit messages of divergent changesets with predecessor as the base. In case of conflicts, we fallback to divergent's commit message which should be changed in future. We should pop up the editor with the commit message and the conflict markers and let user fix that. Tests are added for the functionality added.

Tests for the --stop flag for `hg evolve` command while resolving phase-divergence
==================================================================================

The `--stop` flag stops the interrupted evolution and delete the state file so
user can do other things and comeback and do evolution later on

This is testing cases when `hg evolve` command is doing phase-divergence resolution.

Setup
=====

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

  $ hg init stoprepo
  $ cd stoprepo
  $ echo ".*\.orig" > .hgignore
  $ hg add .hgignore
  $ hg ci -m "added hgignore"
  $ for ch in a b c d; do echo foo > $ch; hg add $ch; hg ci -qm "added "$ch; done;
