IsConstructor returns true for all wrappers that are callable. Wrapped
arrow functions are callable and thus IsConstructor will return true
if given one; however, if we unwrap the arrow function, IsConstructor
will return false. The latter is the correct behavior here.

We already have NonNegativeLength and NonNegativeAu, so we can re-use it
to define the specified value and the computed value of border-spacing.
And then implement ToAnimatedValue for it.

The motivation is that Chrome XBL stylesheets can be parsed under author
level, but we allow some event-state pseudo classes like
:-moz-handled-clicktoplay to be used.
Also synchronize the privilege of pseudo classes in
non_ts_pseudo_class_list.rs and nsCSSPseudoClassList.h (except :fullscreen).

Servo's async Tokenizer: New! Improved! Now with multithreading!
<!-- Please describe your changes on the following line: -->
The Tokenizer, defined in the file `async_html.rs` will run on the main thread, while h5e's `Tokenizer`(along with its Sink) lives on the parser thread. Both h5e's `Tokenizer` and `Sink` communicate with the main thread Tokenizer via their own mpsc channels. The Sink keeps sending parser operations to the main thread, to be executed. For some operations, it waits for a message from the main thread before returning.

Store raw string for prop decl in @supports
This fixes the serialization issue of `@supports` rule that whitespaces are not preserved like in other browsers.
It makes the work a bit redundant (the property name and colon is parsed twice), but I suppose this isn't a big deal.
