Sync with Node.js master

This is just a meta issue to update the whole module. So far it supports parts and other things are missing or somewhat outdated. It would be good to sync the whole project. One of the things that we should look into is what Browser support should be achieved. I personally would like to skip IE support. It is pretty hard to backport all changes that are necessary to support the Internet Explorer 11 (even though the current worldwide usage is still around 3%).
