We might want to consider changing the setup for RefPtrTraits, so that it could work well with certain types of classes, but this patch is taking the approach where one needs to explicitly opt-in classes. Also, see the patch changing nsCOMPtr which makes also that to use same AddRef/Release mechanism. That doesn't not only give consistent behavior, but also helps with performance. Depends on D187147 Differential Revision: https://phabricator.services.mozilla.com/D187148
