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.
Fixes#9220

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.

Use DisplayListSection everywhere
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.

Replace Rc<RefCell<Response>> with Rc<Response>
Similar to why I'm doing #9172, I'm changing `Rc<RefCell<Response>>` into `Rc<Response>` and wrapping fields in `RefCell<T>` as needed. So far I've only needed to change `url_list`, but I'm sure I'll need to update more fields in the future.
There's two lines that don't compile that I'm not going to bother trying to fix until #9172 is approved, because getting them to work now will just require more changes after merging with the changes #9172 makes to them.

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.

Replace Rc<RefCell<Request>> with Rc<Request>
To make using Request easier, I've changed it from an `Rc<RefCell<T>>` to just `Rc<T>`, and updated individual fields to `RefCell<T>` or `Cell<T>` as needed. Git seems to be telling me there's a conflict with request.rs, which I resolved locally, but I'm not sure what to do (if anything) to make it easier to merge.

Correctly handle local sources for CSS3 fonts
Currently, servo panics for me when loading something like this:
```
@font-face {
font-family: "test family";
src: local(test font face);
}
```
That's due to a bug in `FontCacheTask`. `FontCacheTask` tries to get the value for the key
"test font face" from `self.web_families`, but previously initialized a value for the key "test family".
These two commits add an awkward test and fix the bug by not shadowing the variable `family_name`. Since the argument to `local()` should explicitly not be the name of a font family, the previous variable name was wrong and misleading anyways.
