Corresponding Gecko bugs, where @Manishearth has given r+s:
* https://bugzilla.mozilla.org/show_bug.cgi?id=1288302
* https://bugzilla.mozilla.org/show_bug.cgi?id=1310463
(Sorry for the large structs_{debug,release}.rs changes; I thought it was too much trouble to disentangle the useless changes from the legitimate ones.)
Holding off on landing this until the Gecko patches are reviewed and landed.

Only traverse elements from style
This is part of the new incremental restyle architecture work. I have patches to element-ify things more, but want to get this in the tree first.

Instead of maintaining a dummy restyle damage field for text nodes, we can just
perform the necessary parent inheritance and is_changed adjustments on the fly
in ThreadSafeLayoutNode, simplifying the requirements on the style system.

incremental restyle: Introduce StylingMode and deprecate explicit dirtiness
This is another chunk of work to move us toward the new incremental restyle architecture.
Eventually, we'll make a fine-grained decision at each node about what style to recompute based on the RestyleHint on the node data (along with other things). For now, we use the existence of RestyleData as a coarse-grained approximation of this.

Use enum BorderWidth instead of a tuple-like struct to store the specified
value. BorderWidth is needed to be used in both longhand and shorthand
border width properties, so I put it in `specified` module.
Fixed#13869.
Prefer auto-generation for some keyword props

Simplify TNode a bit, removing has_changed from style
A couple of changes here:
* Remove the option to unset with the dirty bit settes.
* Add an explicit API for setting text node style.
* Hoist has_changed handling into the restyle damage setter and text node style setter.
* Make set_style take a non-Option.
