Merge r1535532 from trunk:

 * r1535532
   Make the certificate verification handling in ra_serf properly ask multiple
   providers for acceptance of certificate failures.
   Justification:
     Without this patch it is not possible to have one hook accept invalid
     ca roots, while another provider accepts an invalid date on a certificate.
     Probably only interesting for bindings and code that explicitly tests
     our certificate handling behavior.
