Update gdk-pixbuf and gdk-pixbuf-gnome to 0.17.  Changes include:

* Merged the endianness conversion fixes from the GDK version into the
  Xlib version; oops (Federico).

* Merged fixes from GTK+ 2.0

* Minor documentation improvements (Federico).

* Fixed endianness conversion in the 16-bit gdk-pixbuf-drawable
  functions (Federico).

* Minor fixes for the IBM/AIX compiler (Christian Schaller).

* The image loaders are now linked against the pixbuf and GTK+
  libraries so that the Python bindings work (Johan Dahlin).

* Backported the BMP loader from GTK+ 1.3 (Federico).

* Added support for BI_BITFIELDS coding to the BMP loader [Ximian bug
  #12125] (Federico).

* Fixed stupid bug in the ICO loader.  ICO pixbufs should always have
  an alpha channel [Ximian bug #11224].  (Federico)

* Slight tweaks to the documentation Makefile.  (Federico)

* Added support for 16-bpp BMPs and ICOs (Federico).

* Added support for 32-bpp ICOs (Federico).

* Use the correct visual and colormap for the pixbuf-demo widgets

* Install the headers in a versioned directory so that they don't
  collide with the GNOME 2 platform (Havoc).
