* Infrastructure to warn about the use of deprecated preprocessor make
  variables.
* Use that infrastructure to war about MPI_CPPFLAGS.

[[Imported from SVN: r5807]]

  - Introduce autoconf substitutions DUNEMPICPPFLAGS, DUNEMPILDFLAGS and
    DUNEMPILIBS.
  - Deprecate MPI_LDFLAGS and MPI_CPPFLAGS: the automake manual recommends
    against "_" in names of such variables, MPI_LDFLAGS actually contains
    mainly libraries and simply changing MPI_LDFLAGS to MPI_LIBS will probably
    break a lot of stuff.  By deprecating MPI_CPPFLAGS it is possible to make
    the preprocessor generate a deprecation warning with instructions to
    change both MPI_CPPFLAGS and MPI_LDFLAGS (though this has yet to be
    implemented).

* bin/dunedoxynize reads a file doc/doxygen/Doxylocal
* it merges the file dune-common/doc/doxygen/Doxystyle
* it write Doxyfile.in

* every module uses either the alyout from dune-common or dune-web
* .wmlrc is not necessary anymore

[[Imported from SVN: r5622]]

* Turn STRIP_CODE_COMMENTS on in Doxyfile.in.  Otherwise, doxygen seems to
  remove comments from \code...\endcode blocks.  This has the side effect that
  comments are no longer stripped from the source code doxygen presents via
  the web interface, which is probably a good thing in itself.

how it works

[[Imported from SVN: r5591]]

- buggy (see FS 590)
- crappy
- not supposed to be in dune-common anyways
