This puts a few commonly used `Node` helpers into a trait (`NodeTraits`) and gives them more descriptive names and documentation. The renames: - `document_from_node` -> `NodeTraits::owner_document` - `window_from_node` -> `NodeTraits::owner_window` - `stylesheets_owner_from_node<T:` -> `NodeTraits::stylesheet_list_owner` - `containing_shadow_root` -> `NodeTraits::containing_shadow_root` Signed-off-by: Martin Robinson <mrobinson@igalia.com>
