Let's keep this CL to only removing the API. If you want to push to make the
context const, let's do this separately.

 
   // List of |NavigationEntry|s for this controller.
   std::vector<std::unique_ptr<NavigationEntryImpl>> entries_;
 
   // An entry we haven't gotten a response for yet.  This will be discarded
   // when we navigate again.  It's used only so we know what the currently
   // displayed tab is.
   //
   // This may refer to an item in the entries_ list if the pending_entry_index_
   // == -1, or it may be its own entry that should be deleted. Be careful with
