Log Message:
Catch up Upstream svn repository.

(1) Use recent version of automake and autoconf

(2) Add coding-system conversion to tc-bushu.el
   -- This is kind of interim solution, the mechanism
   for the necessity is not really figured out.

(3) Divide  *.el file to be byte compiled and not be compiled.
    other than acinclude.m4, but Makefile.am for now.
  -> patch-lisp_Makefile.am

(4) Update PLIST
   - catch up changes
   - sync with not byte compiled *.el
  
tc-is2{0,1,2}.el is to be byte compiled-by-emacs-version.
But this mechanism is now seemed to be broken.
All are not byte-compiled for work around.
