tests: port test-doctest.py from core hg

We already have a doctest string for evolve.obshistory.cyclic(), but of course
it didn't actually run. Something like test-doctest.py is first needed to run
doctests via run-tests.py.

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

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 orphan resolution.

Setup
=====

  $ . $TESTDIR/testlib/common.sh

  $ cat >> $HGRCPATH <<EOF
  > [extensions]
  > evolve =
  > EOF

#testcases inmemory ondisk
#if inmemory
  $ cat >> $HGRCPATH <<EOF
  > [experimental]
  > evolution.in-memory = yes
  > EOF
#endif

  $ 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;

Testing `--stop` when no evolve is interrupted
==============================================

  $ hg evolve --stop
  abort: no interrupted evolve to stop
  [255]

Testing with wrong combinations of flags
========================================

  $ hg evolve --stop --rev 1
  abort: cannot specify both "--rev" and "--stop"
  [255]

  $ hg evolve --stop --continue
  abort: cannot specify both "--stop" and "--continue"
  [255]

  $ hg evolve --stop --all

Testing when only one revision is to evolve
