Hi all,
This is take 4 on VNC authentification.
The specification is as mentioned at
http://lists.xensource.com/archives/html/xen-devel/2006-09/msg00666.html
(However, password came to describe plain text)
The difference is follows.
- protocol_authtype() without the necessity was deleted.
- The check on the protocol version was added.
- And, some small modification.
Thanks all.

Best regards,
Watanabe
