evolve: support successors of ancestor of orphan with multiple roots

The previous code checked that the set of successors has a single root.
However, there’s no reason to require that in general.

Example:

o 6
|
o 5
|\
| o 4
| |
o | 3
|/
| * 2
| |
| x 1
|/
o 0

1 is obsoleted by 3, 4 and 6. We are considering the case when 2 gets evolved.

The roots are [3, 4] and the heads are [6]. Before the change, the user was
asked which destination to choose, but there was only one choice (6). After the
change, 6 is chosen as the destination.

  $ hg init server

Try the multiple ways to setup the extension

  $ hg -R server log --config 'extensions.evolve.serveronly='
  $ hg -R server log --config "extensions.evolve.serveronly=${SRCDIR}/hgext3rd/evolve/serveronly.py"
  $ PYTHONPATH=$HGTEST_ORIG_PYTHONPATH hg -R server log --config "extensions.evolve.serveronly=${SRCDIR}/hgext3rd/evolve/serveronly.py"

setup repo

  $ echo "[extensions]" >> ./server/.hg/hgrc
  $ echo "evolve.serveronly=" >> ./server/.hg/hgrc
  $ hg serve -R server -n test -p $HGPORT -d --pid-file=hg.pid -A access.log -E errors.log --traceback
  $ cat hg.pid >> $DAEMON_PIDS
