		- (fill_host_and_class_id): only fill in client and class IDs if
			they are set by callers.

	* dhcpcd/client.c
		- (class_id_setup): don't autogenerate a class ID, only use one
			we're given, if any.
		- (client_id_setup): don't autogenerate a client ID, only use one
			we're given, if any.

	* dhcpcd/dhcpcd.c
		- (dhcp_interface_init): ensure that client options are correctly
			NULL terminated

	* src/NetworkManagerDHCP.c
		- (nm_device_dhcp_request): pass hostname to dhcp library
