This will run Servo with browser.html. We use the latest package in the
dependency tree if there are multiple copies, since there is no way for
Cargo to tell us which one is canonical.
Fixed compile error in generated code, when webidl constructors have same number of args
One of the ways that generated code differentiates constructors is by comparing if the args are array-like. The generated code was calling a function `IsArrayLike` that no longer exists. I re-implemented it with a more rust-like naming scheme.

Fix animation smoothness when using requestAnimationFrame.
Previously, the flow for ticking animations was:
Compositor -> Constellation -> Layout -> Script
However, this means that the compositor <-> layout messages can thrash, meaning layout thread is very rarely idle.
This means that the script thread (which joins on the layout thread during reflow) was unable to execute and run rAF callbacks.
With this change, the flow is now:
Compositor -> Constellation -> Script (when rAF is active).
Compositor -> Constellation -> Layout (when transitions / animations are active and no rAF is present).
This makes rAF based animation *much* smoother.

Suppress reflows before RefreshTick or FirstLoad
This fixes a bug where partially loaded content is displayed to the user
before it should be, usually before stylesheets have loaded. This commit
supresses reflows until either FirstLoad or RefreshTick, whichever comes
first.

Unfortunately, hit_test and mouse_over did not do reflows if they were
necessary, and so by suppressing the initial spurious reflows, these
methods started to panic without a display list to query. This patch
also transforms these into queries similar to the other existing
queries.

Optimize flat display lists
Flat display lists were a 2x regression on the spheres demo. This patch series fixes that.
See the individual commits for more details.

`memmove` was showing up high in the profile when concatenating and
shorting display lists. This change drastically reduces the `memmove`
cost in exchange for some minor additional allocation cost.
script: Fix MouseOver handling
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

I'm in the process of making the binding generator easier to use, so that we can check it
into the tree. More patches in that direction soon, but I wanted to first just update the
existing bindings to match the state of the world in gecko.
