Issue 5593 - Use messaging in popup for prefs, whitelisting, and stats

ext/popup.js

   // Calling i18n.getMessage from the background page causes Edge to throw an
   // exception.

   window.ext.i18n = chrome.i18n;

   // to send messages the local "chrome" namespace must be used.

While moving this function around anyway, how about just removing it, and
calling window.close() directly, as discussed before on another review?

OK, this should happen naturally now after changeset b615bfdf4897 is merged into
master.

+
+  window.ext.prefs = {
+    get(key, callback)
+    {
+      chrome.runtime.sendMessage({type: "prefs.get", key}, callback);
+    },
+    toggle(key, callback)
+    {
+      chrome.runtime.sendMessage({type: "prefs.toggle", key}, callback);
+    }
+  };

IMO, this doesn't belong into ext. Prefs are part of the application logic, not
the abstraction layer.

I've moved it into popup.js now.

+
+  window.ext.createPageObject = tab =>
+  {
+    if (!tab)
+      return null;
+
+    // Create a lightweight page object that resembles ext.Page, but with only
+    // an id and an optional url property.
+    let page = {id: tab.id};
+
+    if (tab.url)
+      page.url = new URL(tab.url);
+
+    return page;
+  };
 }());
