Xft2 and fontconfig conversion, based largely on a patch
        from Keith Packard.

        Xft checks to switch for Xft2 using pkg-config.

        modules/{arabic,basic,hebrew,indic,tamil}/Makefile.am
        pango/Makefile.am: Reflect new Xft/fontconfig dependencies.

        * pango/pangoxft-private.h pango/pangoxft-fontmap.c
        modules/arabic/arabic-xft.c modules/indic/indic-xft.c:
        Switch over to using Xft2 and fontconfig.

        * pango/pangoft2.c pango/pangoft2-fontmap.c pango/pangoft2-private.h
        pango/pango/Makefile.am: Remove usage of mini-xft in
        favor of fontconfig.

        * pango/pango-ot.h pango/opentype/pango-ot-info.c pango/pangoxft.h
        modules/arabic/arabic-{xft,ft2}.c modules/indic/indic-xft.c:
        Attach OpenType information directly to the FT_Face
        structure using FT_Generic.

        * modules/tamil/Makefile.am modules/tamil/tamil-xft.c
        configure.in: Remove this module, no longer needed.
