2. Move the test harnesses into test/. …

   This is preparation for removing the `servo-` prefixes from the various
   Servo components.

4. Introduce a phantom type to prevent script from accessing the layout … …

   …data directly.
   
   Nodes are now parameterized over a "View" type. The particular View type
   determines which methods can be called. Layout data accessors and mutators are
   only accessible to nodes with a LayoutView. The only way to convert a
   `Node<ScriptView>` to a `Node<LayoutView>` is through a transmutation, which is
   done at the moment the layout task receives nodes. (This should be factored
   better to contain the unsafety.)
   
   We should also lock down DOM node mutation to the ScriptView to forbid data
   races, but this patch doesn't do that.
   
   This also reduces coupling between DOM and layout. Soon I would like to move
   the DOM into its own crate, and this is a step on the way of doing that.

   Eventually, the layout interface will be moved along with the DOM into a
   separate crate.

7. Remove the layout debug methods. …

   Premature abstraction; nothing used the traits polymorphically. Furthermore,
   they increased coupling between layout and the DOM.
