dagutil: remove heads() and localsubset from revlogdag.__init__ The previous commit removed the last consumer of this API. I'm not going to mark as API incompatible because I doubt anybody used this functionality (outside of possibly passing an argument to revlogdag.__init__). I intend to remove revlogdag later in this series and its API annotation will cover this one. Differential Revision: https://phab.mercurial-scm.org/D4320
