Otherwise, tests like the following fail, given we always match as unvisited,
and we'd never mark the link as needing invalidation.
<!doctype html>
<style>
a {
color: red !important;
}
.foo :visited {
color: green !important;
}
</style>
<div>
<a href="https://google.es">visit me</a>
<button onclick="this.parentNode.className = 'foo'">Then click me</button>
</div>

This is needed for the omta test to pass. This is pretty much the equivalent to
the old restyle hints code.

This commit also removes the old restyle_hints module and splits it into
multiple modules under components/style/invalidation/element/.
The basic approach is to walk down the tree using compound selectors as needed,
in order to do as little selector-matching as possible.

Pass URL to Browser::new(), delegate url checking logic to 3rd party
<!-- Please describe your changes on the following line: -->
1. Move the logic of computing the initial url from `opts.rs` to `/ports/servo/main.rs`
2. Add a `ServoUrl` argument to `Browser::new`
Based on the requested changes by @paulrouget:
>We can read the pref in main() instead. shell.homepage would be used if the url is not passed as an argument. I'm trying to decouple the "app" logic and the "web engine" logic. I think it's up to the app to set the initial URL, and I'm not sure the initial url should be part of opts.
