Cancelable promises

As a heads up, there's some debate around the fetch() API how exactly
request termination should work and how that affects promises:

The WebRTC WG has also been discussing canceling in the context of
terminating a request for permission from the user. I think they
decided to postpone for now until there's a bit more progress on what
cancelable promises means, but I would not expect everyone to wait
forever.
