pull: move pulled subset into the object

We compute the set of local changeset that were target of the pull. This is then
used by phases logic to decide which part of the history should have it phase
updated.

We move this information into the object to allow extraction of phase
synchronisation in its own function.

I expect obsolete marker exchange to use it too in the future.
