------- Additional Comments from Patrik Persson <patrik.j.persson at ericsson.com>
To solve the short-term issue of client-side storage/databases in
sandboxes, this patch makes sandboxed frames work as if though
client-side storage/databases were disabled in Settings.

Changes:

* SecurityOrigin::equal() and SecurityOriginHash no longer know about
  sandboxing.

* DOMWindow attributes localStorage and sessionStorage are null in
  sandboxed frames.

* DOMWindow method openDatabase() returns null in sandboxed frames.

* Revised test case for sandboxed storage and database
  (LayoutTests/fast/frames/sandboxed-iframe-storage.html).
