evolve: use `merge.graft` instead of `rebasenode`

The core mechanism is properly factorised and have a more stable API.
This is also a good step toward removing the dependency between evolve and the
rebase extension.

This also avoid a breakage with the future 3.3 where some of the rebase API
changed.
