	* dbus/dbus-auth.c (handle_server_data_stupid_test_mech): Just get
	credentials from our currently running process.
	(get_word): Fix a buglet where we were copying the entire length
	instead of relative to our position.

	* dbus/dbus-hash.c (_dbus_hash_test): Don't try to allocate the
	keys on the stack... it's 640k of data.

	* dbus/dbus-sysdeps.c (_dbus_read_credentials_unix_socket): Always
	read the credentials byte off the socket, even if we don't have
	SO_PEERCRED.
	(_dbus_poll): Implement poll() using select() for systems which
	don't have it.

	* glib/test-dbus-glib.c (main): Print out an error if no
	parameters are given.

	* test/data/auth/fallback.auth-script: Added.  Tests that a client
	can fallback to a secondary auth mechanism if the first fails.
