These were moved (unchanged).

This was moved and slightly changed.
|data| was a cookie rather than CookieDetails
but only the CookieDetails were needed - so
the type of the param changed.

+  var out = [];
+  var fields = cookieInfo[data.type];
+  if (fields)
+  for (var field of fields) {
+    // Iterate through the keys found in |cookieInfo| for the given |type|
