More nesting plumbing. Still does nothing because we don't parse the
nested rules.
Should be trivial to prove this patch doesn't change any behavior so
far, but I want to land it on its own because it can have performance
implications.
This follows the pattern of what we do with other rules like layers and
container conditions, that is, keep the ancestor selectors in a stack,
and poke at the last one in order to replace the ancestor.
This changes the behavior of replace_parent_selector as with the newer
version of the spec, stuff like:
div {
.foo {
stuff
}
}
Should work as `div .foo`. A test is added for this case.

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.
