Fetch cancellation
This PR implements cancellation for fetch, and uses it for XHR. This means that fetch clients can now send a message to the fetch task asking for the network request to be aborted.
Previously, clients like XHR had abort functionality but would implement it by simply ignoring future messages from the network task; and would not actually cancel the network fetch.

Continue http cache work
<!-- Please describe your changes on the following line: -->
Work in progress, and not quite worth a review yet. (Continuation of https://github.com/servo/servo/pull/4117)
TODO
- [ ] cache metadata (find some subset of`net_traits::Metadata` that can be shared across threads, it seems the problem is mainly stuff inside `hyper::header` in the `headers` field)
- [ ] determine which other fields of a `Response` need to be cached, so a full and valid one can be returned upon a cache hit.
- [ ] determine how to best share the cache across fetch threads (inside HttpState like I tried now?)
- [ ] Spend more time reading the spec and make sure the cache follows it where it matters.
- [ ] Make the current wpt tests pass.
- [ ] More...

Fixes warnings from rust-lang/rust#44229 when `--enable-commonmark` is
passed to rustdoc.
This is mostly a global find-and-replace for bare URIs on lines by
themselves in doc comments.
Update http_network_or_cache_fetch according to spec
There are still many steps blocked by the absence of an HTTP cache and the inability to trigger a credentials dialog.

We need to switch to tungstenite to finally update openssl, this commit
rewrites the whole websocket infrastructure to properly follow the Fetch
spec and to make switching to a different websocket library easier.
