* This function decodes a DER-encoded CrossCertPair pointed to by

* (possibly empty) pointed to by "certList". If none of the objects
* can be decoded into a Cert, the List is returned unchanged.
*
* PARAMETERS:
* "derCCPItem"
* The address of the SECItem containing the DER representation of the
* CrossCertPair. Must be non-NULL.
* "certList"
* The address of the List to which the decoded Certs are added. May be
* empty, but must be non-NULL.
* "plContext"
* Platform-specific context pointer.
* THREAD SAFETY:
* Thread Safe (see Thread Safety Definitions in Programmer's Guide)
* RETURNS:
* Returns NULL if the function succeeds.
* Returns a CertStore Error if the function fails in a non-fatal way.
* Returns a Fatal Error if the function fails in an unrecoverable way.
