- Update IsErrNotFound() to check for the current type before falling back to
detecting the deprecated type.
- Remove unauthorizedError and notImplementedError types, which were not used.
- IsErrPluginPermissionDenied() was added in 7c36a1af03,
but not used at the time, and still appears to be unused.
- Deprecate IsErrUnauthorized in favor of errdefs.IsUnauthorized()
- Deprecate IsErrNotImplemented in favor of errdefs,IsNotImplemented()
