Bug 1424834 - Replace nsHostRecord.callbacks with LinkedList<RefPtr<nsResolveHostCallback>> r=mayhemer * nsResolveHostCallback extends nsISupports (for addref-ing and because nsDNSAsyncRequest implements nsICancelable) * nsResolveHostCallback extends LinkedListElement<RefPtr<nsResolveHostCallback>> so the list can properly manage references * nsDNSAsyncRequest and nsDNSSyncRequest properly implement nsISupports and use RefPtr to manage lifetimes MozReview-Commit-ID: 5NvBcWZzfyN
