Is it correct that there is no simple way to create a 
gnutls_pk_params_st ? gnutls_pk_params_init and gnutls_pk_params_release 
is all there is?

gnutls_rsa_params_t and gnutls_x509_privkey_t seems to be very similar 
to gnutls_pk_params_st, but the types seems be held very separate with 
no simple conversions?

It seems like it could be nice to use something like a cousin of 
gnutls_rsa_params_import_raw. Or how could you imagine that 
gnutls_pk_params_st based RSA keys could be handled?
