D1191: obsfate: makes successorsetverb takes the markers as argument

REVISION SUMMARY
  Right now, successorsetverb only needs successors to compute the verb. But we
  will want use additional information (effect-flags and operation) in the near
  future to compute a better verb.
  
  Add the markers parameter now so extensions (like Evolve) could wrap the
  function and start experimenting around better obsfate verbs.
  
  As successorsetverb now takes both successorset and markers parameters, rename
  it to obsfateverb, successorsetandmarkersverb was too long.
