+johnme for notifications
+mkwst, mostly for CallbackPromiseAdapter.h

I really don't like that I have to add yet another CallbackPromiseAdapter
overload :-(. My template fu is not good enough to know whether this can be
solved with some magic though, and this is still better than brewing an own
solution.

non-owner lgtm for WebNotificationManager.h (didn't review
CallbackPromiseAdapter in detail)

LGTM. Overloading it here is probably fine, as I also can't think of a
template-based solution off the top of my head. You might be well-served to ping
jyaskin@ or the like.
