A CAdES Basic Electronic Signature (CAdES-BES) contains, among other specifications, a collection of Signing Certificate reference attributes, stored in the signedData ether as ESS signing-certificate or as ESS signing-certificate-v2. These are described in detail in Section 5.7.2 of RFC 5126 - CMS Advanced Electronic Signatures (CAdES). This patch adds support for adding ESS signing-certificate[-v2] attributes to CMS signedData. Although it implements only a small part of the RFC, it is sufficient many cases to enable the `openssl cms` app to create signatures which comply with legal requirements of some European States (e.g Italy).
