ARGUMENTS
       gnutls_x509_crt_t cert

       unsigned int * critical

DESCRIPTION
       This function will return certificates CA status, by reading the
       basicConstraints X.509 extension (2.5.29.19). If the certificate is a

       the certificate does not have CA flag set.  A negative error code may
       be returned in case of errors.  If the certificate does not contain the
       basicConstraints extension GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE will
