Add history information to mozbrowserlocationchange event
This is a change in the Browser API itself.
Before, on `mozbrowserlocationchange`, we would call `getCanGoBack()` and `getCanGoForward()`. Two asynchronous methods called on an event, which doesn't make much sense, especially because we already know on `mozbrowserlocationchange` if we can go back/forward. So here I'm adding 2 new properties to the event to tell if the iframe can go back/forward.
The way `event.detail` is defined also changed. Before, `event.detail` was a string (the new uri), now it's an object (`{uri:String,canGoBack:bool,canGoForward:bool}`).
This is one of the design flaw of the early Browser API: not using objects for the detail property, making it hard to extend the event payload.
So that makes this event not backward compatible. We can:
1. just don't care. It's up to the client to test if event.detail is a string or not if it needs to be compatible with Gecko
2. fix it in Gecko. The client will still have to test `event.detail` to make it compatible with older version of gecko
3. rename `mozbrowserlocationchange` to something else (`mozbrowserlocationchange2` ?)
Please advise.

layout: Skip layout traversals that obviously won't do anything.
This reduces CPU usage when mousing over simple pages (example.com). More complex pages (Wikipedia) still reflow a lot due to other bugs.
Additionally, this change causes Servo to stop painting the results of hit test queries. This is also a win for CPU usage.
This significantly improves #9999, though there's more that can be done. I'll leave it open in case @paulrouget thinks this PR isn't enough.

Remove HTMLCollectionElementsRevIter
It's almost a duplicate of HTMLCollectionElementsIter, aside from that its node_iter is a PrecedingNodeIter. We can simply use dynamic dispatch for node_iter instead of making it a concrete type.

implement and use From<bool> for enum and back
as discussed in the #servo channel on IRC:
implement and use `From<bool>` for `EventBubbles` (and back direction)
implement and use `From<bool>` for `EventCancelable` (and back direction)

Update WebSocket blocked ports to match the Fetch spec
Adresses #9949.
This adds a function that tests whether a request should be blocked or not based on it's url's scheme and port. It also adds testing for port restriction to the `main_fetch` method. More info in eb07418c83.
@Ms2ger In https://github.com/whatwg/html/issues/841, @annevk proposes to remove port restrictions from websockets. Should we go ahead do that, given that the spec hasn't been changed yet?

Add the scrollWidth and scrollHeight extensions to the element interface
Add the `scrollWidth` and `scrollHeight` extensions to the element interface. My goal was to create a method that encompassed getting `scrollWidth`, `scrollHeight`, `scrollTop`, and `scrollLeft`.
I also noted that `clientHeight` and `clientWidth` to not handle the root element and the body element correctly.

Moved synthetic_click_actiavtion out of Activatable trait so it can be
called by all elements (not just activatable). Calls appropriately
from click. Also updates the isdisabled check in click to check for all
types of elements
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.

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.
