style: Stop using PseudoElement::inherits_all.
This was done that way just because Servo didn't support the `all` property at
the time.
We should do it this way and optimize it if it's slow. Though I suspect that
most of stuff doesn't actually need to be inherited, my patch at bug 1498943
should make it much faster than what it would otherwise be.

DevTools - add Emulation Actor
Last one for today, this one adds the Emulation actor, which allows the netmonitor panel to load. The emulation actor has no methods for now, but will eventually be used by the netmonitor to throttle connections.
Currently the netmonitor shows but doesn't have any values. will get to that soon!

Combined with the changes for the stylesheets actor, the device actor, and the extra methods added in browserContext and threadActor, the devtools are now all loading \o/

DevTools - add Interrupt method to ThreadActor
This is one of three pull requests that allows the DevTools Debugger to render.
The two related prs are #21942 and #21943
In this pr, I introduced the `interrupt` method to the threadActor. This is arguably a carry-over from the firefox devtools, where the debugger server is running in the same event loop as the content scripts, and it can only update itself when the debugger server is paused. Depending on how debugging is, or how debugging will be implemented on servo, this method may need to be adjusted for "debugger events" and "script events".
After all three patches on this topic are merged, you should be able to see the debugger \o/ (but no sources yet)

DevTools - add ListWorkers method to BrowsingContextTargetActor
This is one of three pull requests that allows the DevTools Debugger to render.
The two related prs are #21942 and #21944
This pr introduces a `ListWorkers` method, which the debugger relies on for startup. At the moment, we are returning an empty array, but later on we can return an array populated by all workers associated with a target.

DevTools - add DeviceActor and update Root to own global actors
This is one of three pull requests that allows the DevTools Debugger to render. This pr also introduces global actors to the root actor, the same as exists in FF devtools. At a later point I would like to reorganize this.
The two related prs are #21943 and #21944
This is the most significant change of the three. It introduces both Device and Performance as global actors, and leaves the Performance actor also as a target actor. It also introduces the concept of ownership to the root actor, with regards to the two Global Actors.
The Device actor as added to allow the JS Debugger to start up. This required the DeviceActor's `getDescription` method. `getDescription`, in the case of servo, returns a couple of basic fields that the debugger is interested in but doesn't use, specifically `apptype` -- which is returning a fake value of `servo`, and the version number `63.0`.
The version number is interesting because devtools has [dropped support for any versions below 2 version numbers from the current firefox](https://searchfox.org/mozilla-central/rev/3a54520d8d2319a4116866371ed3d9ed2ec0cc2b/devtools/client/debugger/new/src/client/firefox/commands.js#398).
This means that if we want the servo server to be supported, we will need to keep this number synced with FF's versioning. It isn't great, but hopefully we can introduce a different approach later on.

DevTools - add preliminary StyleSheetActor
Based on an error coming from devtools, that the server did not support a stylesheets actor, this patch introduces a [StyleSheetsActor](https://searchfox.org/mozilla-central/rev/26b40a44691e0710838130b614c2f2662bc91eec/devtools/server/actors/stylesheets.js#590-853). It has no methods yet, but it is a small step towards getting the devtools up and running.
Before the change:
No stylesheet editor
After the change we can see that the style editor now loads. It has no information but I will get to that later.
<img width="902" alt="screen shot 2018-10-14 at 12 51 51" src="https://user-images.githubusercontent.com/26968615/46915813-61192900-cfb1-11e8-8382-3d9dc8db4114.png">
Status after this PR:
* Debugger does not load
* Netmonitor does not load
* Console is loading but doesn't receive messages.
* Inspector is, but does not have any information
* style editor is *now loading* but does not have any information
* Performance is an out of date tab, and will likely need to be changed substantially
next steps for this will be to implement the [protocol methods](https://searchfox.org/mozilla-central/source/devtools/shared/specs/stylesheets.js#74-95)
I am not too sure how to test this, it doesn't look like there are tests yet for the devtools, is that right?

Make layout use available image data before querying the image cache.
These changes make layout more efficient for any page which contains images that have already loaded, since it does not require synchronously querying the image cache thread for each image present. It also makes reloading a page actually display the images that are already in the image cache.
