bookmarks: consider successor changesets when moving bookmark (issue4015)

Previously, this required -f because we didn't consider obsolete changesets
(and their children ... or successors of those children, etc.). We now use
obsolete.foreground to calculate acceptable changesets when advancing the
bookmark.

Test coverage has been added.
