/* CBS_asn1_ber_to_der reads an ASN.1 structure from |in|. If it finds
* indefinite-length elements then it attempts to convert the BER data to DER
* and sets |*out| and |*out_length| to describe a malloced buffer containing
* the DER data. Additionally, |*in| will be advanced over the ASN.1 data.
*
* If it doesn't find any indefinite-length elements then it sets |*out| to
* NULL and |*in| is unmodified.
*
* A sufficiently complex ASN.1 structure will break this function because it's
* not possible to generically convert BER to DER without knowledge of the
* structure itself. However, this sufficies to handle the PKCS#7 and #12 output
* from NSS.
*
* It returns one on success and zero otherwise. */
