EmailProcessor.php/CiviMailProcessor.php passing incorrect $params

I discovered this when trying to get the double opt-in profiles patch (CRM-7465) to work - it appears that the Mailer.php $params signature was changed and SoapServer.php was updated to match, but EmailProcessor.php/CiviMailProcessor.php were left with the old style, which breaks this functionality (double opt-in has no effect on group membership status, as suggested by Alex in CRM-7465). As far as I can tell, this issue is present on both stable and trunk code. I have included a patch for the "confirm" path that works for me, but it looks like some of the other $params need updating also (I would do this, but I am unsure of how to test each case).
