tests: add a test file `--abort` flag while resolving phase-divergence

This patch adds a new test file test-evolve-abort-phasediv.t which will contain
tests for `hg evolve --abort` flag while resolving phase-divergence.

There is a case in this test which does not work right which will be fixed in
upcoming patches.

+Tests for the --abort flag for `hg evolve` command while phase-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 phase-divergence resolution.
+
+Setup
+=====

+  $ cat >> $HGRCPATH <<EOF

+  > 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;
