topic: add a simple option to reject publishing

The option is pretty basic but it can be used as base to build larger feature.
The main target for going in this direction is to be able to distinct between
user that are "simple contributors" pushing topic for review and the
"maintainers" or "automation" that can publish changesets.

test of the split command

Basic case, split a head
  $ hg init testsplit
  $ cd testsplit
  $ mkcommit _a
  $ mkcommit _b
  $ mkcommit _c --user other-test-user
  $ mkcommit _d
  $ echo "change to a" >> _a

To create commits with the number of split
  $ echo 0 > num
  $ cat > editor.sh << '__EOF__'
  > NUM=$(cat num)
  > NUM=`expr "$NUM" + 1`
  > echo "$NUM" > num
  > echo "split$NUM" > "$1"
