backport 924447 and subsequent build fixes:

fix a memleak caused by a shared_ptr cycle: Resource holds a Model copy, which has a shared_ptr<ModelPrivate>, which in turn has a shared_ptr to the 
resources.
That way RDF models never got destructed. Break the cycle by holding weak_ptr's to ModelPrivate in Resource and Statement. That would break cases 
where only a ResourcePtr is kept and no Model copy, thus keep a Model copy in ResourceWrapper so that the model is not destroyed until the last 
Resource/ResourceWrapper refering to that model goes out of scope.
