Tracing down some things to add in validators and I''ve run across something that kinda bothers me... In order to implement validators you have to override the clone method. The directors seems to be set up to specifically handle this situation. However, whenever C++ calls back to the object''s methods the swig_get_up function is returning false. It seems like swig_up

This is a WIP version of the series I've been working on for a while now to get all of the atomic DRM drivers in the tree to use the atomic MST helpers, and to make the atomic MST helpers actually idempotent. Turns out it's a lot more difficult to do that without also fixing how port and branch device refcounting works so that it actually makes sense, since the current upstream
