Why do we need another namespace?  We shouldn't have nested namespaces in
Chromium code in any case.

Frankly, we're trying to kill the chrome:: namespace as well, so I'd remove both
these namespaces.

Code moved so this namespace is not necessary.

-void RegisterTabStripLayoutTypePrefs(PrefRegistrySimple* registry);
+// Registers local state preferences specific to the TabStrip.
+void RegisterPrefs(PrefRegistrySimple* registry);
 
+// Converts possibly existing value for tabstrip layout type into a boolean
+// value indicating stacked layout preference.
+void MigratePrefs(PrefService* pref);
