This is definitely and absolutely the plan, and why changes will not
come fast.

I'll send an e-mail to have this discussion once I'll have more concrete
plans but I have on my mind following rules of thumb:

- introduce API (aka client/server communication) and repo versioning
(independent from actual rdiff-backup version)
- any breaking change must go over 3 versions of rdiff-backup, so that
version N can handle N-1 and N+1
