Complained by autoconf 1.14, cf. FS#1462.

This reverts commit 901b5954.
It (METIS) does not seem needed for compilation and the patch
forced the user and downstream modules to add additional compile
 and linker flags.

This reverts commit 6132d0df.

Unlike the original METIS/ParMETIS scotch does not use extern "C"
in its headers. This lead to linker errors as descibed in
http://lists.dune-project.org/pipermail/dune/2014-March/012745.html.
This patch fixes this by guarding the includes with an extra extern "C"
directive.

Just like for the autotools.

For HAVE_METIS we do not use the ENABLE trick. It is therefore either defined or
not. Therfore using "#if HAVE_METIS" is a bug. This patch fixes this.

There were problems with repartition.hh when using the original parmetis. The cause was
that for scotch we need to require both parmetis.h and metis.h, which broke backwards
compatibility for the original parmetis (which worked without metis, too). With the patch
we check whether parmetis.h is from scotch and if that is the case also require metis. If not,
metis suffices.

Reformat whole CMakeLists.txt file for better readability.

GCC warned about ambiguity between builtin operator*=(double&, int)
and FieldVector<double,i>::operator*=(int), but at least picked one
and just emitted a warning. Clang instead errored out.

To fix this this patch explicitly uses a floating point dampening
factor in the additive version of the AMG.

Fixes flyspray #1456

To test the implementation improved the test to not only include diagonal block matrices on the
diagonal, because with diagonal left/right multiplication does not make a differece.

The warning has to be silenced by using DUNE_UNUSED_PARAM in dune-common.
This fixes FS#1431.

It was moved to dune-common in Dune 2.3.

Since revision 8df1d996 overlappingschwarz
with UmfPack was broken due to renaming an internal variable accessed by a friend.
This patch fixes this by adding a new private method to access the internal matrix
of solver and uses that for the assembly.

This the customized rest of Rene's patch. To make doxygen happy
we use DUNE_UNUSED_PARAMETER.

In addition each residual is only printed once now.

Some cmake specific dirs have been deleted in commit c66db537
but not removed from configure.ac resulting the build process to fail for the autotools.

Previously, the macros were installed to $(datadir)/cmake/. As we have
some macros in DUNE that might also be in other packages
this may cause conflicts in package managers. With this patch we install
them to $(datadir)/dune/cmake to resolve this issue. Together with the
last patch this will resolve problems  outlined in flyspray

I apologize for givin the wrong task number in the previous patch.

Previously, the macros were installed to $(datadir)/aclocal. As we have
some macros in DUNE that are also installed for some Linux distributions
