	* src/srp-gen.c (main_argp_parser): By default, use transport
	syntax when writing to stdout, and canonical syntax when writing
	to a file.

	* src/server_session.c (do_open_session): assert() that
	connection->user is non-NULL.

	* src/lshd.c (lshd_connection_service): Use
	connection_require_userauth. 
	(main): Allow user's to request ssh-connection service without
	first executing the ssh-userauth protocol. This makes sense if SRP
	was used for key exchange. lshd_connection_service checks that the
	user is properly authenticated before actually starting the
	service. 

	* src/lsh.c (lsh_options): New attributes with_userauth and service. 
	(options2service): New command.
	(make_lsh_userauth): New expression.
	(make_lsh_connect): Use options2service.
	(main_options): New flags --publickey, --userauth, --no-userauth.
	(CASE_FLAG): New macro.
	(main_argp_parser): Implemented --userauth and --no-userauth
	options, with defaults depending on whether or not SRP is being
	used.
	Use the CASE_FLAG macro.
	(request_userauth_service): New global command object.
	(request_connection_service): New global command object.
	
	* src/connection_commands.c (connection_require_userauth): New command.
	(make_connection_if_srp): New function.

	* src/connection.h (CONNECTION_SRP): New constant.

	* src/client_keyexchange.c (do_srp_client_proof_handler): Set
	CONNECTION_SRP flag.
	* src/server_keyexchange.c (do_srp_server_proof_handler):
	Likewise. 

	* src/client.h (request_service): Moved class declaration here.
	(do_request_service): Added prototype and made non-static.
	(STATIC_REQUEST_SERVICE): New macro.

	* src/command, src/connection.c, src/exception.c, src/io.c,
	src/keyexchange.c, src/keyexchange.h, src/lsh_keygen.c,
	src/lshd.c, src/publickey_crypto.h, src/server_session.c,
	src/server_userauth.c, src/server_userauth.h, src/sexp.c,
	src/sexp_parser.c, src/spki.c, src/spki_commands.c,
	src/srp_exchange.c, src/tcpforward.c, src/werror.c: Removed old

	GROUP_ADD. 
	Use new SRP-related atoms. More debug output.

	* src/srp-gen.c (make_srp_gen_options): Use make_ssh_ring_srp_1().
	Use the sexp_format() function.
	
	* src/sexp_commands.c (do_print_raw_hash_to): Use the sexp_format
	function, rather than invoking the SSH_FORMAT method directly.
	* src/spki_commands.c (do_spki_encrypt): Likewise.

	* src/server_userauth.c (userauth_handler): New attributes
	service_e and auth_e. WE use different exception handlers when
	invoking the AUTHENTICATE method and when invoking the service.
	(do_userauth_continuation): Simplified this continuation. It is
	passed a user, and returns the connection.
	(do_handle_userauth): When a service is eventually invoked, it is
	passed a single argument: the connection. Previously, the user
	object was passed as argument to the service.
	(do_userauth): Clear the user attribute of the connection, and
	display a warning message if the connection was already
	authenticated.
	(do_userauth): Don't call make_userauth_continuation() here.

	* src/server_session.c: Deleted user attribute.
	(make_server_session): Deleted user argument.
	(open_session): Deleted user attribute.
	(make_open_session): Deleted user argument.
	(server_connection_service): #if:ed out
	(spawn_process): Added user argument.
	(do_alloc_pty): Use CAST macro. Get the user from the connection
	object.
	(pty_request_handler): Statically allocated object, replaces the
	make_pty_handler function.

	* src/server_keyexchange.c (do_srp_server_proof_handler): Store
	the authenticated user in the connection object.

	* src/publickey_crypto.c (make_ssh_ring_srp_1): Use the generator
	5. Unlike 7, 5 is a primitive root.

	* src/lshd.c: Adapted to the simplified userauth-service
	framework. Deleted lshd_services and calls to
	make_server_connection_service. 

	* src/lsh.c (main_argp_parser): Use new srp-related atoms.

	* src/dh_exchange.c (dh_hash_digest): Added debug-message.

	* src/client_keyexchange.c (do_handle_srp_reply): Check return
	value from srp_make_client_proof().

	* src/atoms.in: Renamed srp-group1-sha1 -> srp-ring1-sha1,
	ssh-group1 -> ssh-ring1.
