remove will_become_orphaned_pgrp()

remove will_become_orphaned_pgrp()

[William Lee Irwin III]

will_become_orphaned_pgrp()'s sole use is is_orphaned_pgrp(). Fold its
body into is_orphaned_pgrp(), rename __will_become_orphaned_pgrp(), and
adjust callers. Code shrinkage plus some relief from underscore-itis.
