Move fringe handling vars and code to new file fringe.c.
(handle_display_prop): Handle left-fringe and right-fringe
display properties; store user fringe bitmaps in iterator.
(move_it_in_display_line_to): Handle cursor in fringe at eob.
(clear_garbaged_frames): Set force_flush_display_p if resized.
(redisplay_window): Redraw fringe bitmaps if not just_this_one_p.
(display_line): Handle cursor in fringe at eob.
(display_line): Set row user fringe bitmaps from iterator.
