        Store builtin stock icons in an icon cache, instead of
        populating a hash table with pixbufs at startup, to save both
        memory and startup time.

        * gtk/stock-icons/*: Reorganize the icons in a directory structure
        suitable for gtk-update-icon-cache, and rename them to match the
        stock ids.

        * gtk/gtkiconcache.[hc]: Support non-mmapped icon caches, and
        add _gtk_icon_cache_has_icon_in_directory().

        * gtk/updateiconcache.c: Support a --source <VARIABLE> argument
        to store the contents of the icon cache in a C header.

        * gtk/gtkbuiltincache.h: Generated private header which contains
        the icon cache for the builtin icons.

        * gtk/gtkicontheme.c: Create a GtkIconCache for the builtin
        icons, and use that in addition to the hash table whenever
        builtin icons are searched.

        * gtk/gtkiconfactory.c: Add GTK_ICON_SOURCE_STATIC_ICON_NAME and
        use it for static stock ids.
        (get_default_icons): Don't add the builtin
        icons to the icon theme, just register the stock ids.
        (render_fallback_image): Take the fallback image out of the
        builtin icon cache.

        * gtk/Makefile.am: Remove stock-icons from SUBDIRS and add
        the necessary machinery to rebuild gtkbuiltincache.h.
