Zach Hoffman 356e886d26 style: Record attribute dependencies within the selector list of :nth-child(... of <selector list>) 
There are separate filters for IDs, classes, attribute local names, and
element state.

Also, we invalidate siblings of elements matched against the selector
list of :nth-child(... of <selector list>) by marking matched elements
with NODE_HAS_SLOW_SELECTOR_NTH_OF.

The only remaining invalidation case invalidation case is
`:nth-child(An+B of :has())` (bug 1818155), which should not block
shipping `layout.css.nth-child-of.enabled`, because :has(...) is still
being implemented (bug 418039).

Depends on D172352

rust-selectors

CSS Selectors library for Rust. Includes parsing and serialization of selectors, as well as matching against a generic tree of elements. Pseudo-elements and most pseudo-classes are generic as well.

Warning: breaking changes are made to this library fairly frequently (13 times in 2016, for example). However you can use this crate without updating it that often, old versions stay available on crates.io and Cargo will only automatically update to versions that are numbered as compatible.

To see how to use this library with your own tree representation, see Kuchiki’s src/select.rs. (Note however that Kuchiki is not always up to date with the latest rust-selectors version, so that code may need to be tweaked.) If you don’t already have a tree data structure, consider using Kuchiki itself.
