Dear all,

@Anders: thanks for merging the RSASSA-PSS definitions :-)

now that pss is in, the certificates in CI+ messages can be dissected. The
attached patch extracts them and calls the X.509 dissection.

I looked at ssl, isakmp and others for examples. hf variables for the
certificates are FT_NONE, dissect_x509af_Certificate()'s parameter implicit_tag
is set to false.

Sample capture file is attached. Please note that one of the certificates
contains non-standard extensions which cause a warning. I'll add support for
those later (once I understand a good way how to do this).

Best regards,

   Martin
