bundle2: introduce an "applybundle" function

There is a case where the intent is clear and the transaction is not optional. We
want to be able to alter that transaction in a wide and easy way. We cannot get
a unified '.apply(repo)' method for bundle1 and bundle2 yet because the api are
still a bit too far apart. But this is a good step forward to get the rc out.
