DESCRIPTION
This function can be used to set a callback to retrieve the username
and password for client PSK authentication. The callback's function
form is: int (*callback)(gnutls_session_t, char** username, gnutls_da-
tum_t* key);
The username and key ->data must be allocated using gnutls_malloc().
The username should be an ASCII string or UTF-8 string. In case of a

ror.
