template: add the obsfate template

Reuse _getobsoletefate and nextvisiblesuccessors to easily get the
obsolescence fate of any node. The limitation is that obsfate is as precise as
these two functions, which is not great for nextvisiblesuccessors.

Test that evolve related algorithms don't crash on obs markers cycles
