The check gets removed from dune-common, thus ISTL has to call it itself.

Previously, the macros were installed to $(datadir)/aclocal. As we have
some macros in DUNE that are also installed for some Linux distributions
this caused conflicts in package managers. With this patch we install
them to $(datadir)/dune/aclocal to resolve this issue outlined in flyspray
task 1409
https://dune-project.org/flyspray/index.php?do=details&task_id=1409

Restores the old twolevelmethodtest and adds a new one to test multithreaded
computation. Fixes the autotools build system to run the multithreaded tests
too. Furthermore introduces multithreaded test with superlu/umfpack.

This patch removed the tests for umfpack from dune-istl as they
are already needed in dune-common. There are modules using umfpack
that do not require dune-istl. Therefore dune-common seems to be the
more appropriate place for the test.

This commit contains
- a wrapper for the C library UMFPack
- tests for both CMake and autotools to find UMFPack on the system
- a unit test for UMFPack
- a new MatrixType ColCompMatrix which is a base class for a column
  compressed matrix. SuperLUMatrix now inherits from this base class.
  This way, no code is duplicated for the very similar interface in
  UMFPack.
- the SuperLU-specific part of OverlappingSchwarz code is abstracted
  to work with either SuperLU or UMFPack

The code was developed by Theo Aouidet, Stefan Bayha, and Dominik Ull
during their software internship at the IPVS in Stuttgart.
