Now we only query for the topmost node, and apply the hover state to all
of the parent elements.
This fixes things like #9705, where the hover state was applied only to
the children.
This also makes us more conformant with other browsers in the case of
taking in account margins and paddings.
For example, prior to this PR, when your mouse was over the inner
element, in the bottom part, `hover` styles didn't apply to the parent.
```html
<style>
div {
padding: 10px;
margin: 10px;
height: 15px;
background: blue;
}
div:hover {
background: red;
}
</style>
<div>
<div></div>
</div>
```
Fixes#9705

Instead of producing a tree of stacking contexts, display list
generation now produces a flat list of display items and a tree of
stacking contexts. This will eventually allow display list construction
to produce and modify WebRender vertex buffers directly, removing the
overhead of display list conversion. This change also moves
layerization of the display list to the paint thread, since it isn't
currently useful for WebRender.
To accomplish this, display list generation now takes three passes of
the flow tree:
1. Calculation of absolute positions.
2. Collection of a tree of stacking contexts.
3. Creation of a list of display items.
After collection of display items, they are sorted based upon the index
of their parent stacking contexts and their position in CSS 2.1
Appendeix E stacking order.
This is a big change, but it actually simplifies display list generation.

Rebase of #7267. Fixes#3598.
This avoids all of the sketchy issues of trying to read the style data for margins from the script thread. I replaced it with a layout query that fetches the margin style properties for a given element.

This commits updates rust-selectors to use the generic parser, and as
such it moves the element state into the style crate.

This fixes about 130 clippy lints. Let me know if i should split up the commit.
I wasn't sure about some of the changes, especially map_or instead of map(...).unwrap_or(...) and if let instead of single arm match were not always a strict improvement in my opinion, but i'll leave that decision to the reviewer :)
There are about 150 lints left which i thought were clippy bugs or i didn't know how to fix.

Separated layout-specific messages to the constellation out from the `ScriptMsg` enum into a `LayoutMsg` enum within `script_traits/script_msg.rs`, addresses [#8843](https://github.com/servo/servo/issues/8843).
I initially tried to move `LayoutMsg` into `layout_traits/lib.rs`, but this introduced a cyclic dependency: `layout_traits` depends on `script_traits` for the `LayoutTaskFactory` implementation, and `script_traits/script_task.rs` now depends on `LayoutMsg` for new layout channels in `InitialScriptState` and `ScriptTask`.

This gets us to where we need to be in order to write a Gecko implementation of the layout wrapper and have things Just Work.
Note that this is somewhat more than we need for just running the style system. But there wasn't a clean place to cut, and I thought it was a good idea to just do a complete job on it now, which may save us effort and mismatches in the long run.

This means we only deal with TrustedNodeAddress in LayoutTask::handle_reflow,
which is where the safety of this usage is guaranteed (by the ScriptReflow
destructor).

This was causing a bunch of tests in tests/wpt/web-platform-tests/html/semantics/embedded-content/the-canvas-element/size.attributes* to fail. They were returning "auto" instead of the correct size. They still fail because the returned size is off by a few pixels, not sure why yet. But this is more correct and may fix other failing tests.

This reduces some unnecessarily tight coupling, makes it clearer what these functions do, and may help avoid bugs where we would return from such a function without updating the relevant field.
It is also a precondition for some future experimentation I'm thinking of doing with this querying design.
