[getdns-api] Distinguish strings from wire format in conversion functions

[Willem Toorop]

Maybe we should use bindatas for the wire format arguments. This is the
form that dnames will be given to the user by the response object (in
"name" and "qname" attributes and in rdata fields that contain dnames):

getdns_return_t getdns_convert_dns_name_to_fqdn(
    const struct getdns_bindata *dns_name_wire_fmt, char** name);

getdns_return_t getdns_convert_fqdn_to_dns_name(
    const char *fqdn_as_string, struct getdns_bindata **dns_name);

What do you think?
