     [auth2.c auth2-chall.c channels.c channels.h clientloop.c dispatch.c]
     [dispatch.h kex.c kex.h packet.c packet.h serverloop.c ssh.c]
     [sshconnect2.c]
     Conformance fix: we should send failing packet sequence number when
     responding with a SSH_MSG_UNIMPLEMENTED message. Spotted by
     yakk@yakk.dot.net; ok markus@
