Bug 1580316 - Update signatureInfo to Array of Array of nsIX509Cert(in raw bytes) r=keeler,dimi The signatureInfo that has been used in ExternalHelperAppService and ReputationService has been stored Array of nsIX509CertList, which isn't necessary because only the raw bytes of the certs are required. This patch intends to remove the usage of nsIX509CertList and store the raw bytes directly. Differential Revision: https://phabricator.services.mozilla.com/D44243

     * Initializes the transfer with certain properties.  This function must

     *
     * @param aSource The source URI of the transfer. Must not be null.
     *
     * @param aTarget The target URI of the transfer. Must not be null.
     *
     * @param aDisplayName The user-readable description of the transfer.
     *                     Can be empty.
     *
     * @param aMIMEInfo The MIME info associated with the target,
     *                  including MIME type and helper app when appropriate.
     *                  This parameter is optional.
     *
     * @param startTime Time when the download started (ie, when the first
     *                  response from the server was received)
     *                  XXX presumably wbp and exthandler do this differently
     *
     * @param aTempFile The location of a temporary file; i.e. a file in which
     *                  the received data will be stored, but which is not
     *                  equal to the target file. (will be moved to the real
     *                  target by the caller, when the download is finished)
     *                  May be null.
     *
     * @param aCancelable An object that can be used to abort the download.
     *                    Must not be null.
     *                    Implementations are expected to hold a strong
     *                    reference to this object until the download is
     *                    finished, at which point they should release the
     *                    reference.
     *
     * @param aIsPrivate Used to determine the privacy status of the new transfer.
     *                   If true, indicates that the transfer was initiated from
     *                   a source that desires privacy.
