Fix for document salvageable state
I noticed a bug where if the document was un-salavageable due to the presence of `beforeunload` listeners, this could be overwritten if there were no listeners for `unload`. This could also have happened if an iframe of the document had no listeners while the parent did.

Implement MutationObserver.disconnect()
<!-- Please describe your changes on the following line: -->
This implements https://dom.spec.whatwg.org/#dom-mutationobserver-disconnect
I added a `node_list` to the `MutationObserver` struct to keep track of the nodes involved in an observer because otherwise I could not find a way to unregister the observers on the node themselves without traversing the whole document tree. Let me know if there's something I missed.

0 is not among the valid values for a wrap mode or filter, so it won't
ever be returned unless the driver is broken, and even if it was a
valid value we would want to pass it through.
MutationObserver api: Implement takeRecords() and characterData mutations
<!-- Please describe your changes on the following line: -->
I started by looking at adding support for `takeRecords()` to get fluent.js to work on Servo. To get the wpt tests to pass I ended up implementing character data mutations (most of the plumbing was already there) and this fixed a few more tests.
We are still missing support for `disconnect()`, which I keep for a followup.
