        Bug 143542 – PangoFT2Fontmap leak

        * pango/fonts.c:
        * pango/pangoatsui.c (pango_atsui_font_finalize),
        (_pango_atsui_font_set_font_map):
        * pango/pangocairo-font.c (_pango_cairo_font_get_metrics),
        (_pango_cairo_font_private_get_hex_box_info):
        * pango/pangocairo-win32font.c (_pango_cairo_win32_font_new):
        * pango/pangofc-font.c (pango_fc_font_get_metrics):
        * pango/pangofc-fontmap.c (pango_fc_font_map_add),
        (_pango_fc_font_map_remove), (cleanup_font):
        * pango/pangowin32-fontmap.c (pango_win32_font_neww),
        (pango_win32_font_map_real_find_font):
        * pango/pangowin32.c (pango_win32_font_finalize):
        * pango/pangox-fontmap.c (pango_x_font_map_load_font):
        * pango/pangox.c (pango_x_font_new), (pango_x_font_finalize):
        Make the reference the font->fontmap reference weak.

        The code for setting the reference must look like this:

          g_assert (font->fontmap == NULL);
          font->fontmap = (PangoFontMap *) fontmap;
          g_object_add_weak_pointer (G_OBJECT (font->fontmap), (gpointer *) (gpointer) &font->fontmap);

        And releasing it like:

          g_assert (font->fontmap != NULL);
          g_object_remove_weak_pointer (G_OBJECT (font->fontmap), (gpointer *) (gpointer) &font->fontmap);
          font->fontmap = NULL;

        I have converted all fontmaps.  The win32 and atsui ones can
        use some simple testing.

        The PangoFc fonts actually don't need the weakref as the fontmap
        already provides a similar link by itself.
