Implement browsing context discarding <!-- Please describe your changes on the following line: --> Implement browsing context discarding (https://html.spec.whatwg.org/multipage/browsers.html#discard-a-document). * When a pipeline is closed, inform the script thread whether the browsing context is to be discarded. * In script threads, synchronously discard any similar-origin documents and browsing contexts. * When a browsing context is discarded, it loses the reference to the active document, but the window keeps it, so we need to move the `Document` pointer from `BrowsingContext` to `Window`. * Fix the webIDL for Window to make parent and top optional (the spec says they can return null when the browsing context is discarded). --- <!-- Thank you for contributing to Servo!
