Dirty elements whose selectors are affected by sibling changes
This fixes incremental layout of nodes that match pseudo-class selectors such as :first-child, :nth-child, :last-child, :first-of-type, etc. Fixes#8191 and other intermittent layout bugs.
This code is based on the following flags from Gecko:

Depends on servo/rust-selectors#71. r? @SimonSapin
There are a couple of TODO items in this commit, but I'd appreciate feedback on the general approach before I finish it up. (Also, if someone who knows more than I do could give some advice about atomic orderings...)

Stop returning an Option from Window::browsing_context.
A Window always has a WindowProxy; the only reason it's wrapped in a nullable
field is the order in which those objects are created.

According to JSProxy.h, without this the default implementation calls
ownPropertyKeys and filters out the unenumerable properties. We know when such
things exist so we don't need to do that.
Implement XHR::SetRequestHeader Step 3
Closes#9548.
Alternative implementation of #9595.

I'm not sure if a utility method on `ByteString` is the best place for this functionality, maybe a free function in XHR module would be more suitable.
Also where would be the correct place to add a test for this functionality (if required)?

Timers clean up
This PR splits the `ActiveTimers` abstraction into
- `OneshotTimers` for scheduling "arbitrary" oneshot timers, such as XHR timeouts, and
- `JsTimers`, based on `OneshotTimers`, for scheduling JS timers (`setTimeout`/`setInterval`).
The result is mich cleaner and the timer initialization steps now closely resemble the specification.
**Notes**
- The second and third commit are strictly renames and code rearrangements.
- I'm not particularily happy with the `OneshotTimerCallback` enum and its circular dependency with `XHRTimeoutCallback`, but I couldn't come up with anything better.

The code was split into the following two abstractions.
- OneshotTimers can be used to schedule arbitrary oneshot timers, such
as XHR-Timeouts.
- JsTimers (`setTimeout` and `setInterval`) which use OneshotTimers to
schedule individual callbacks.
With this change the implementation (of JsTimers in particular) is in
much closer alignment with the specification.
Add methods to move ByteStrings underlying bytes
Add methods to move the underlying `Vec<u8>` for `ByteString`.
I saw this as at least two methods. One to "move and replace with and empty Vec<u8> (`bytes`), and one to take ownership of the whole object (`own_bytes`). I typically also don't like adding methods with out unit tests. If you think they're unnecessary, just let me know.
As always, please let me know if you have any comments, critiques, or nits!
Fixes#9655

Add WebRender integration to Servo.
WebRender is an experimental GPU accelerated rendering backend for Servo.
The WebRender backend can be specified by running Servo with the -w option (otherwise the default rendering backend will be used).
WebRender has many bugs, and missing features - but it is usable to browse most websites - please report any WebRender specific rendering bugs you encounter!

Implement planned navigation
Fixes#3648.
Note that I have only implemented "mutate action URL" and "get action URL". The remaining ones can have E-less easy issues created for them.
