Previously the module path was a relative to the install
directory. With this patch the CMake package configuration file contains the
full path and the macros are found.

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

Find<Package>.cmake modules, as they were missing with set
CMAKE_DISABLE_<Package>=TRUE.

Now they are in speparte modules Add<Package>Flags and thus can be
used as exspected with disabled packages.

Update test to conform common style.
Changed user variable SUPERLU_DIR to SUPERLU_PREFIX.

[[Imported from SVN: r1731]]

This was due to the fact that find_<lib|file>(varname ...) sets
${varname} to varname-NOTFOUND if nothing is found.
Therefore using the variable varname in
CMAKE_REQUIRED_<LIBRARIES|INCLUDES> is a really bad idea.

We are preventing this now by checking the variables first.

- Make CMake module installation path configurable
- Detect CMAKE_MODULE_PATH automatically
  + First call find_package(dune-common) to query its CMAKE_MODULE_PATH
  + Then setup the module path
  + After each find_package of dune module update the CMAK_MODULE_PATH
  + each module exports ist own <package-name>_MODULE_PATH in the

These leads to kind of weired variabable names (dune-common_DIR,
dune-common_LIBRARIES, etc.) but finds non-installes modules
easier. You just sets CMAKE_PREFIX_PATH to the directory containing
the modules.
