Generates a PKCS #7 signed data message.
 This method is used when the signature has already been generated.
 The signature, the signer's details, and optionally a signature
 timestamp and the content that was signed, are all packaged into a
 signed data message.
- Parameters:
- parameters- The non-null input parameters.
- omitContent- true if the content should be omitted from the
         signed data message. Otherwise the content is included.
- applyTimestamp- true if the signature should be timestamped.
         Otherwise timestamping is not performed.
- Returns:
- A PKCS #7 signed data message.
- Throws:
- NoSuchAlgorithmException- The exception is thrown if the signature
         algorithm is unrecognised.
- CertificateException- The exception is thrown if an error occurs
         while processing the signer's certificate or the TSA's
         certificate.
- IOException- The exception is thrown if an error occurs while
         generating the signature timestamp or while generating the signed
         data message.
- NullPointerException- The exception is thrown if parameters is
         null.
