Fix authentication bypass bug
...
The client could bypass the password check by continuing after getting error
from the server and guessing the network parameters. The server would still
accept the rest of the setup and also network traffic.
Add checks for normal and raw mode that user has authenticated before allowing
any other communication.
Problem found by Oscar Reparaz.

Add support for using an unspecified RR type
...
Add PRIVATE query type with id 65399 (private use range).
According to RFC3597 the reply data in a query with unspecified RR type must be handled
as unstructured binary data, which means it can contain raw packet data just like the NULL type.
Since the reply format is optimal it is ordered just after NULL in the priority order.
