1895257 - Implement navigation methods from Navigation API

Status: NEW

(Core :: DOM: Navigation, task)

Description

[Andreas Farre [:farre]]

Since all of the navigation methods will probably share functionality we'll implement them together. In case of segmented landing make sure to split off bugs for each separate method.

  NavigationResult navigate(USVString url, optional NavigationNavigateOptions options = {});
  NavigationResult reload(optional NavigationReloadOptions options = {});

  NavigationResult traverseTo(DOMString key, optional NavigationOptions options = {});
  NavigationResult back(optional NavigationOptions options = {});
  NavigationResult forward(optional NavigationOptions options = {});
