This function will copy the name of the Certificate in the provided buffer. The name will be in the form "C=xxxx,O=yyyy,CN=zzzz" as described in RFC4514. The output string will be ASCII or UTF-8 encoded, depending on the certificate data. The buf returned will be null terminated and the buf_size will account for the trailing null. If buf is null then only the size will be filled. This function does not output a fully RFC4514 compliant string, if that is required see gnutls_x509_crt_get_dn3().
