setdiscovery: use a revset for finding DAG heads in a subset...

setdiscovery: use a revset for finding DAG heads in a subset The march towards moving away from dagutil continues. Like other patches moving us away from dagutil, there is the potential for regressions to occur because revlogdag's headsetofconnecteds() uses revlog.index, which doesn't take filtering into account. The revset layer does. But no tests fail, so we appear to be in the clear. Differential Revision: https://phab.mercurial-scm.org/D4317
