* keyboard.c: Don't undef SIGIO

* s/darwin.h (NO_SOCK_SIGIO): Define NO_SOCK_SIGIO on carbon
* Makefile.in (mac.o): Depend on blockinput.h and atimer.h.
       (macfns.o): Don't depend on ccl.h.
* macfns.c (mac_frame_parm_handlers): Set handlers for
Qleft_fringe and Qright_fringe.
* macterm.c (mac_fill_rectangle_to_pixmap)
(mac_draw_rectangle_to_pixmap, mac_copy_area_to_pixmap)
(mac_copy_area_with_mask_to_pixmap, x_draw_image_foreground_1):
Put in #if 0.
(mac_scroll_area) [TARGET_API_MAC_CARBON]: Use ScrollWindowRect.
(x_flush) [TARGET_API_MAC_CARBON]: Don't traverse frames.
(XFlush) [TARGET_API_MAC_CARBON]: Define to an empty replacement.
(x_draw_glyph_string_background, x_draw_glyph_string_foreground)
[!MAC_OS8]: Added ifdef'd out code for os8.  Don't use
XDrawImageString.  Always draw background and foreground separately.
(x_draw_image_foreground): Use clipping instead of computing the
intersection rectangle.
(x_draw_image_glyph_string): Don't draw an image with mask to a
pixmap.
(x_redisplay_interface): Set flush_display_optional member to 0.
(XTread_socket): Correctly reset the TEConverter
