We use alert() to communicate test results to wptrunner. Unfortunately,
sometimes the alert output is interleaved with other output on stdout,
causing wptrunner to classify the test result as a timeout. I hope this will
avoid that scenario.
It's not possible to correctly determine during the css cascade whether the container height
is explicitly specified. Additionally, the spec https://drafts.csswg.org/css2/visudet.html#the-height-property
says this should affect the *used* height, rather than the computed height.
This significantly improves the layout in #6643.
layout: Tie transitions to the DOM node and finish them instantly when new styles are set.
Tying transitions to the DOM node avoids quadratic complexity when
updating them.
Finishing transitions instantly when styles are updated makes our
behavior more correct.

Obey Strict-Transport-Security header
Resolves#6703.
Done:
* [x] When STS headers received, add the host to the HSTS list
Todo:
* [ ] Persist the in-memory list so that it's reloaded on the next browser boot
* [ ] Add tests to `http_loader::load` - it's pretty well completely untested right now, but it's a bit gnarly to untangle and without mocking, it's hard to deal with the dependency on making a real network request. Writing a mock request object should be doable for testing, but there's a lot going on in the function right now.

script: Use `Arc::make_unique` instead of `Arc::get_mut` when updating inline styles.
Transitions make the reasoning in the comment in the relevant sections
not true.

style: Switch animation timestamps to be doubles instead of floats.
32-bit floats are not enough to hold timestamps since the epoch and
result in jank.

Persuading devtools to communicate with the workers; r=jdm
For now, this just gives some purpose to the abandoned receiver and later selects over the two receivers (for #6767). (oh wait, forgot to check the local build - there are still a few errors)...

script: Make the resource task communication use IPC channels.
This change makes Servo use serialized messages over IPC channels for resource loading. The goal is to make it easier to make Servo multiprocess in the future. This patch does not make Servo multiprocess now; there are many other channels that need to be changed to IPC before that can happen. It does introduce a dependency on https://github.com/serde-rs/serde and https://github.com/pcwalton/ipc-channel for the first time.
At the moment, `ipc-channel` uses JSON for serialization. This is because serde does not yet have official support for bincode. When serde gains support for bincode, I'll switch to that. For now, however, the JSON encoding and decoding will constitute a significant performance regression in resource loading.
To avoid having to send boxed `AsyncResponseTarget` trait objects across process boundaries, this series of commits changes `AsyncResponseTarget` to wrap a sender only. It is then the client's responsibility to spawn a thread to proxy calls from that sender to the consumer of the resource data. This only had to be done in a few places. In the future, we may want to collapse those threads into one per process to reduce overhead. (It is impossible to continue to use `AsyncResponseTarget` as a boxed trait object across processes, regardless of how much work is done on `ipc-channel`. Vtables are fundamentally incompatible with IPC across mutually untrusting processes.)
In general, I was pretty pleased with how this turned out. The main changes are adding serialization functionality to various objects that `serde` does not know how to serialize natively—the most complicated being Hyper objects—and reworking `AsyncResponseTarget`. The overall structure of the code is unchanged, and other than `AsyncResponseTarget` no functionality was lost in moving to serialization and IPC.

Use local slice_chars
StrExt::slice_chars is deprecated and will be removed in Rust. This
lifts the implementation from Rust libstd and puts it in util::str.
This fixes a bunch of deprecation warnings in Servo.

Send display lists over IPC in multiprocess mode.
This patch set introduces the `--multiprocess` (`-M`) switch. Right now, all it does it cause display lists to be serialized, but eventually it will cause actual processes to be spawned.
