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 So far it supports parts and other things are missing or somewhat outdated.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%).

Start by comparing the whole module with the Node.js master implementation and inventory the missing or outdated parts. Then clarify the browser support target, especially whether Internet Explorer 11 is excluded. Done means the module is synced and its supported browser range is agreed and reflected in the work.
