following bug 740079 To get along with the synchronous `status' property, it would be nice to support `onstatuschange' callbacks. There are a few use cases where this would be easier than a set of onconnect / onconnecting / ondisconnect / etc. event listeners and it would be more XHR-like.

This should be pretty straightforward. The one thing I wondered about was whether it was worth it to change the internal (IPC) notifications to follow the DOM API. I decided against it since not all of the notifications did exactly the same thing (in particular, disconnect is handled a little differently). Any opinions on that would be welcome.
