	* dbus/dbus-message.c: use message->byte_order instead of
	DBUS_COMPILER_BYTE_ORDER throughout.
	(dbus_message_create_header): pad header to align the
	start of the body of the message to 8-byte boundary

	* dbus/dbus-marshal.h: make all the demarshalers take const
	DBusString arguments.

	* dbus/dbus-message.c (_dbus_message_loader_return_buffer):
	validate message args here, so we don't have to do slow validation
	later, and so we catch bad messages as they are incoming. Also add
	better checks on header_len and body_len. Also fill in
	message->byte_order

	* dbus/dbus-string.c (_dbus_string_validate_utf8): new (not
	implemented properly)
	(_dbus_string_validate_nul): new function to check all-nul

	* dbus/dbus-marshal.c (_dbus_marshal_get_field_end_pos): rename
	get_arg_end_pos and remove all validation
	(_dbus_marshal_validate_arg): actually do validation here.
