absolutely-positioned flows separately when storing overflow.
This code dates back to the time when absolutely positioned flows were
ignored by all of their ancestors up to the containing block. This
hasn't been true for at least a year.
Closes#9306.
Closes#9309.
Is a partial fix for #9308.
Add Partial Implementation of style DOM traits for Gecko, and some basic glue to let Gecko call into Servo
The wrapper stuff is partially-complete, modulo some unimplemented methods. The glue code is just a toy for now. Regardless, I think it's worth getting some of this stuff in-tree to minimize breakage.

The pipeline id stuff is currently unused. If someone needs it, they can add
an additional trait bound on their css error reporter to get the pipeline id.
Move LayerType enum to gfx_trait
The LayerType enum is only used in gfx_traits and layout, so it
shouldn't be defined in msg. Move the definition to gfx_traits
instead.

More aggressively remove Fragment RestyleDamage
Now clean up damage on all fragments that belong to a Flow. This ensures
that damage does not re-propagate up to the parent Flow from the
Fragments. It also means that the flow tree dump should show a more
accurate picture of the state of the flow tree.

DisplayListSection, StackingLevel, and BackgroundAndBorderLevel all
represent pretty much the same thing, a particular section of the
display list. Instead of maintaining three enums which do the same
thing, just use DisplayListSection everywhere. It's a superset of the
other two and this change will make it easier to flatten the DisplayList
in the future for WebRender.
Fix `linear_gradients_lengths_a.html` and fix Servo's use of "background-clip" to actually make it work.
See the commit messages for details.

I forgot to do this along with the parallel case. Ideally I'd merge this patch
into that one, but then I'd need to rebase it over the LayoutContext patch,
which would be a pain.
We do a few things-here:
* Hoist non-layout-dependent fields in SharedLayoutData and LocalLayoutData into style/.
* Hoist parts of css/matching.rs into style/.
* Hoist parts of layout/animation.rs into style/animation.rs.
* Remove the duplicated-but-slightly-different definition of OpaqueNode.
This patch does a number of things, unfortunately all at once:
* Hoists a large subset of the layout wrapper functionality into the style system.
* Merges TElementAttributes into the newly-created TElement.
* Reorganizes LayoutData by style vs layout, and removes LayoutDataShared.
* Simplifies the API for borrowing style/layout data.
There's still more to do to make the style system usable standalone, but
this is a good start.
