This could be solved by removing the JS_FRIEND_API from these member functions. But then I start wondering, isn't marking the entire class as public/friend going to mean every single function in it is going to be exported at library level? That can't possibly be the right action to take...can it?

This patch is sort of mostly fine, if I remove the redundant JS_FRIEND_API on the member functions, I expect. But if we have really managed to slide into exporting every single member function in JSContext, it feels like something has gone terribly wrong somewhere and we should be going home and rethinking our lives.

Will land once those prior patches are landed, just in case one of them is the cause of passingness and un-publicking happened not to be.
