checkheads: check successors for new heads in both missing and common
A relevant obsolete marker may have been added -after- we previously
exchanged the changeset. We have to search for remote heads that
disappear by the sole fact of pushing obsolescence.
This case will also happen when remote got the new version from a
repository that does not propagate obsolescence markers.
