Changes from v2:
     * Many new patches, as the approach is different:
       For one, only replication snapshots that are blocking rollback
       are removed. Second, consider more snapshot candidates when
       probing for an incremental replication base. Last, instead of
       directly running replication after rollback, prevent snapshot
       deletion if it might be the current incremental replication
       base.

Many thanks to Fabian G. for discussing those ideas with me!

All patches are new in v3, except guest-common patch #1, which
hasn't changed much, and would fix some issues already by itself.

I think nothing requires an explicit dependency bump, but some things,
like "remove only the real blockers", will only start working when all
the pieces are in place.
