X509_CRL_get0_by_serial() attempts to find a revoked entry in crl for serial number serial. If it is
       successful, it sets *ret to the internal pointer of the matching entry. As a result, *retMUSTNOT be
       freed after the call.

       X509_CRL_get0_by_cert() is similar to X509_get0_by_serial() except it looks for a revoked entry using the
       serial number of certificate x.

       X509_CRL_get_REVOKED() returns an internal pointer to a STACK of all revoked entries for crl.

       X509_REVOKED_get0_serialNumber() returns an internal pointer to the serial number of r.

       X509_REVOKED_get0_revocationDate() returns an internal pointer to the revocation date of r.

       X509_REVOKED_set_serialNumber() sets the serial number of r to serial.  The supplied serial pointer is
       not used internally so it should be freed after use.

       X509_REVOKED_set_revocationDate() sets the revocation date of r to tm. The supplied tm pointer is not
       used internally so it should be freed after use.

       X509_CRL_add0_revoked() appends revoked entry rev to CRL crl. The pointer rev is used internally so it
       MUSTNOT be freed after the call: it is freed when the parent CRL is freed.

       X509_CRL_sort() sorts the revoked entries of crl into ascending serial number order.

       X509_CRL_get0_by_serial, X509_CRL_get0_by_cert, X509_CRL_get_REVOKED, X509_REVOKED_get0_serialNumber,
       X509_REVOKED_get0_revocationDate, X509_REVOKED_set_serialNumber, X509_REVOKED_set_revocationDate,
       X509_CRL_add0_revoked, X509_CRL_sort - CRL revoked entry utility functions

       Applications can determine the number of revoked entries returned by X509_CRL_get_REVOKED() using
       sk_X509_REVOKED_num() and examine each one in turn using sk_X509_REVOKED_value().

X509_CRL_get0_by_serial() and X509_CRL_get0_by_cert() return 0 for failure, 1 on success except if the
       revoked entry has the reason "removeFromCRL" (8), in which case 2 is returned.

       X509_CRL_get_REVOKED() returns a STACK of revoked entries.

       X509_REVOKED_get0_serialNumber() returns an ASN1_INTEGER structure.

       X509_REVOKED_get0_revocationDate() returns an ASN1_TIME structure.

       X509_REVOKED_set_serialNumber(), X509_REVOKED_set_revocationDate(), X509_CRL_add0_revoked() and
       X509_CRL_sort() return 1 for success and 0 for failure.
