evolve: show unfinished information in `hg status -v` (issue5886)

`hg status -v` shows information about unfinished states or `hg status` shows it
when `commands.status.verbose=True` is set.

Before this patch, information about interrupted evolve does not show up because
evolve does not resgiters in cmdutil.STATES. This patch make sure we register
evolve related information there.

There has been an idea to unify cmdutil.unfinishedstates and cmdutil.STATES
which needs some work and the resulting state does looks a bit complicated. So
till the time we unify them, let's fix this bug by registering in
cmdutil.STATES.

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;
