This removes some very old vestigial code that really should have been
removed during the content addressability transition. It implements
something called "reference" but it behaves differently from the actual
reference package. This was only used by client-side content trust code,
and is relatively easy to extricate.

- some function signatures have changed - use the new ones
- re-generate the notary delegation key certs, since notary doesn't allow SHA1
- fix some error message mapping because now if a root rotation fails to validate trusted operations will fail
