[PATCH/itcl] Update to Itcl 3.3

[Keith Seitz <keiths at redhat dot com>]

Hi,

I've committed a mega-patch (omitted) to update the sourceware Itcl to 
version 3.3. This is needed because Itcl 3.2 does not support TEA (Tcl 
Extension Architecture), which we really need in order to use a 
system-installed Tcl/Tk/Itcl/Itk/Iwidgets.

I have not tested it on Windows (Cygwin or Mingw) yet, so there may be 
problems... I'll try to check these sometime soon.

        Import of Itcl 3.3.
        * itcl/configure.in, itk/configure.in, iwidgets/configure.in:
        Replace with configure.ac.
        * itcl/configure, itk/configure, iwidgets/configure: Regenerate.
        * configure.ac, Makefile.am, Makefile.in: New files.
        * README: "New" file.
        * aclocal.m4: Regenerate.
        * itcl/Makefile.in (RANLIB): Replace with RANLIB_LIB so
        that the toplevel build does not override this variable.
        * itk/Makefile.in (RANLIB): Likewise.
        * itcl/tclconfig/tcl.m4 (TEA_PATH_TCLCONFIG): Look for 
itclConfig.sh
        in the platform-specific location (unix or win).
        (TEA_PATH_TKCONFIG): Likewise.
        (TEA_MAKE_LIB): Even on windows, GCC libraries must start with 
"lib".
        * itk/tclconfig.m4: Copy of itcl/tcl.m4.
        * iwidgets/tcl.m4: Remove.
        * iwidgets/tclconfig: New directory.
        * iwidgets/tclconfig/tcl.m4, iwidgets/tclconfig/install-sh: Copies
        of itcl/tclconfig files.
        * iwidgets/Makefile.in (MKINSTALLDIRS): Use mkdir -p.
        * iwidgets/configure.ac (PACKAGE): Rename to PACKAGE_NAME.
        Call TEA_INIT, add AC_CONFIG_AUX_DIR and AC_PROG_INSTALL.
        Use TEA_* instead of SC_* macros.
        Search a few more directories for the itcl and itk libraries.
