Following up on things that -Xlint told me, sometimes because Mr. Linty
was being sensible and other times just to shut him up so we can hear
better in the future.

- made xml.Equality public because it occurs in public method signatures
- made some actor classes with inaccessible-unoverridable methods final
- eliminated a bunch of "dead code follows" warnings by deleting the
dead code which really did follow - improved the reliability of warnings
about inaccessible types

For the changes in actors, review by phaller.
