Deep copy should always use existing functions that are not ignored

Browse Source 
While testing this fix in OpenShift it was discovered that the
PackageConstraint was overly aggressive - types that declare a public
copy function should always return true.  PackageConstraint is intended
to limit packages where we might generate deep copy function, rather
than to prevent external packages from being consumed.
