Move SSH_MSG_UNEXPECTED generation into the BPP.

Browse Source 
Now I've got a list macro defining all the packet types we recognise,
I can use it to write a test for 'is this a recognised code?', and use
that in turn to centralise detection of completely unrecognised codes
into the binary packet protocol, where any such messages will be
handled entirely internally and never even be seen by the next level
up. This lets me remove another big pile of boilerplate in ssh.c.
