Previously we didn't do this because we didn't want to expose

less risk.

between the client and server, but the error accidentially disabled the
diffie-hellman-group-exchange-sha1 KEX method.
This fixes the client code to use the correct method list, but
because nobody complained, it also disables the
diffie-hellman-group-exchange-sha1 KEX method.

Algorithm lists are now fully expanded when the server/client configs
are finalised, so errors are reported early and the config dumps
(e.g. "ssh -G ...") now list the actual algorithms selected.

aren't full pattern-lists that support negation.
