Tiaan Louw 2a83b583b1 Bug 1771896 - Add simple parsing and matching support for :has r=emilio 
Parsing is behind a config value `layout.css.has-selectors.enabled`. This
change does not support p:has(> a) combinators, but will handle them
gracefully, just not matching on them.

rust-selectors

CSS Selectors library for Rust. Includes parsing and serilization 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.
