This patch adds the cmake findpackage script which locates Tim Davis' SuiteSparsae collection.

If a certain setting of the SuiteSparse library should be used it can be found using
find_package( SuiteSparse COMPONENETS <list-of-components> )
with a specific list of components.
Existence of components can be check using the SUITESPARSE_<comp>_FOUND/HAVE_SUITESPARSE_<comp> cmake variable.

The UMFPack search routines are redirected to the more general FindSuiteSparse script.

Old feature support macros which were tested until 2.4, kept around
for one more release. As these are now always supported due to the
new compiler requirements, they are directly defined without an
explicit test.

These commits broke compiling / linking if one package was found
but the includes / libraries were not added. We need a different
approach to hide the ENABLE_* trick from the user and keep full
testing capabilities.
This reverts commits 0f12caff
and d75c3a46.

If you rely on it, add the deleted CMake files to your module.

They were tested until 2.3 and are now always supported due to
the new compiler requirements.
Removed macros: HAVE_INTEGRAL_CONSTANT, HAVE_DUNE_HASH,
HAVE_STD_HASH, HAVE_TYPE_TRAITS, HAVE_VARIADIC_TEMPLATES,
HAVE_VARIADIC_CONSTRUCTOR_SFINAE, HAVE_RVALUE_REFERENCES

[Typetraits][Compatibility] Provide partial backwards compatibility for is_indexable on old GCC versions

Older GCC versions have some nasty bugs related to SFINAE and indexing
with operator[]. This patch adds a configuration check for those
problems and a partial backwards compatibility hack for those older
compilers that is sufficient for our current use case in the VTK
writer.

GCC 4.4, I'm looking at you

This is e.g. needed for dune-alugrid and might be a first step for
getting rid off the ParMETIS dependency.

Moved from dune-istl's config.h.cmake. Otherwise it cannot
be shared with other modules using ParMETIS.

Macro to use C++11 feature noexcept specifier.
Add test for CMake and autotools.

There is more macro magic to be removed.

With GCC 4.4 or newer HAVE_INTEGRL_CONSTANT, HAVE_STD_HASH, and
HAVE_TYPE_TRAITS is always 1, no further testing necessary.
The test defines will be removed after the next Dune release.

Like 2a4965d9 for autotools.
Cf. FS#1445

Its call was removed from dune_mpi.m4 back in 2012.

Deprecate header and macro dune_static_assert.
Use static_assert instead.

The config.h entry for ENABLE_UMFPACK should be in the same
module as the test for UMFPack, to avoid future conflicts with
multiple modules running the test for umfpack.

If not found, our own fallback implementation will be used.

[Bugfix] Prevent definition of HAVE_BOOST without value due to race conditions in some autoconf versions.

For some autoconf versions there was a race condition between ax_boost_base.m4 and dune_boost_base.m4 resulting in HAVE_BOOST being defined with no value (instead of ENABLE_BOOST). For others there were even two definitions of it (one with and one without value). 

This patch renames the symbol being defined in dune_boost_base.m4 to HAVE_DUNE_BOOST and defines a value for it if boost is found.

Please change your code such the preprocessor directives checking for boost from
#if HAVE_BOOST
to
#if HAVE_DUNE_BOOST

Resolves flyspray 1265 and presumably 1249.
