* xfns.c (x-send-client-message): Moved to xselect.c

(Fx_change_window_property): Add optional arguments TYPE, FORMAT and
OUTER_P.
(Fx_window_property): Add optional arguments TYPE, SOURCE, DELETE_P,
VECTOR_RET_P.  Handle AnyPropertyType.  Call x_property_data_to_lisp
if vector_ret_p is true.
(syms_of_xfns): Sx_send_client_message moved to xselect.c.
