        Patch from James Henstridge to update to automake-1.7
        (#109542)

        * autogen.sh: update to call newer tools.

        * configure.in: various updates, to use M4 macros to put
        variables that change each release at the top.
        Use AC_HELP_STRING to format help strings.
        Use AC_CONFIG_COMMANDS to generate gdkconfig.h.

        * Makefile.am: require Automake 1.7.  Remove gdk-2.0.pc and
        gtk+-2.0.pc on uninstall.  Pass --enable-gtk-doc to configure
        during distcheck.

        * docs/reference/*/Makefile.am: simplify to use the gtk-doc.make
        makefile fragment.

        * */Makefile.am: don't use STRIP_BEGIN/STRIP_END.
        Use BUILT_SOURCES where appropriate.
        Build generated files in builddir rather than srcdir.
        Fix uninstall and distclean targets to satisfy distcheck.

        ===

        * gdk/*/Makefile.am: Remove the hacks to get gdkenumtypes.h
        built first, since we are now using BUILT_SOURCES.

        * gdk/Makefile.am: Remove an outdated comment about gdk_headers.

        * demos/gtk-demo/Makefile.am: Fix srcdir != buildd problem
        with geninclude.pl.

        * configure.in: Update versions to 2.3.0.
