tests: add test about aborting content-divergence when multiple parents

This patch adds tests for --abort flag of hg evolve command when we are
resolving content-divergence which are on different parents and parent of one of
them is the gca of both of them.

The tests shows that we are doing good and we should advertise the flag during
conflicts.

Tests for the --abort flag for `hg evolve` command while content-divergence resolution
======================================================================================

The `--abort` flag aborts the interuppted evolve by undoing all the work which
was done during resolution i.e. stripping new changesets created, moving
bookmarks back, moving working directory back.

This test contains cases when `hg evolve` is doing content-divergence resolution.

Setup
=====

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

  $ hg init abortrepo
  $ cd abortrepo
  $ 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;
