(x_frame_parms): Add `left-fringe' and `right-fringe' parms.

(x_set_frame_parameters): Process Process `font' parameter before other
parameters as fringe widths depend on it.
(x_set_fringe_width): New function.
(x_figure_window_size): Use x_compute_fringe_widths.
(Fx_create_frame): Process `left-fringe' and `right-fringe' frame
parameters.
