bookmark: take successors into account when updating (issue3561)
When we rewrite a bookmarked changeset, we want to update the
bookmark on its successors. But the successors are not descendants
of its precursor (by definition). This changeset alters the bookmarks
logic to update bookmark location if the newer location is a successor
of the old one[1].
note: valid destinations are in fact any kind of successors of any kind
of descendants (recursively.)
This changeset requires the enabling of the obsolete feature in
some bookmark tests.
