not respond to challenge, and later successfully authenticated itself
using another method, the kbdint context would never be released,
leaving the PAM child process behind even after the connection ended.
Fix this by automatically releasing the kbdint context if a packet of
type SSH_CMSG_AUTH_TIS is follwed by anything but a packet of type
SSH_CMSG_AUTH_TIS_RESPONSE.

- The PAM kbdint device sometimes doesn't know authentication succeeded
until you re-query it. The ssh1 kbdint code would never re-query the
device, so authentication would always fail. This patch has been
submitted to the OpenSSH developers.
- The monitor code for PAM sometimes forgot to tell the monitor that
authentication had succeeded. This caused the monitor to veto the
privsep child's decision to allow the connection.
These patches have been tested with OpenSSH clients on -STABLE, NetBSD and
Linux, and with ssh.com's ssh1 on Solaris.
