MDL-24561 forum subscription checks sesskey - backported from 2.0
The only case when sesskey is not available is when we came to
subscribe.php from a link in email. In that case, we display a
confirmation page that redirects back providing the sesskey.
All other links to subscribe.php are fixed now so they provide sesskey
as a parameter.
