buffer-modified-p returning `autosaved'.

restore-buffer-modified-p instead of altering the buffer modiff
(since this has other side effects like not updating after async
`display' changes.

buffer has been autosaved after changes.
(Frestore_buffer_modified_p): Allow adjusting whether the buffer
has been autosaved after changes.

(pgtk_draw_fringe_bitmap):
(pgtk_defined_color): Fix coding style.
* src/dispextern.h (struct glyph_row): New field `stippled_p'.
We cannot just use the contents of the glyph row, since it has
to be set in `gui_clear_end_of_line' and is more convenient to
