[css-values] URLs

It seems http://url.spec.whatwg.org/ can be used now.

What would be useful in due course is having the model of what a style
sheet is better defined.
http://dev.w3.org/csswg/cssom/#css-style-sheets has some of it, but
lacks the actual base URL (different from location, which should
really be named href, I filed a bug on that), and a pointer to the
associated document (you'd have to traverse owner).

Then here you could actually cross-reference "stylesheet"
"stylesheet's url", etc. when resolving these URL values.

It seems something else is actually responsible for fetching these
values. (Some CSS properties seem to use CORS, some no CORS, there
might be some other differences there too.)
