Merge branch 'feature/cleanup-cholmod' into 'master'

Merge branch 'allow-blockvector-of-doubles' into 'master'

ref:core/dune-istl So, for example, you can write

    BlockVector<double>

instead of

    BlockVector<FieldVector<double,1> >

and it will do what you expect it to do. With this patch, any type for which
Dune::IsNumber<T>::value returns true will end the recursion.

See merge request [core/dune-istl!240]

  [core/dune-istl!240]: gitlab.dune-project.org/core/dune-istl/merge_requests/240

Feel free to put the test back in if it does serve a purpose
that I missed.  But please, if you do so please add an
explanation.

The BlockVector capacity is expected to be an unsigned integer.
However, literals like '100' are signed, and therefore triggered
a warning.

So, for example, you can write

  BlockVector<double>

instead of

  BlockVector<FieldVector<double,1> >

and it will do what you expect it to do.

Merge branch 'feature/mtbv-inherit-tuple-constructors' into 'master'

ref:core/dune-istl

-   Makes member function count const
-   Inherits tuple constructors so that MultiTypeBlockVector can be
    constructed from existing Vectors, or we can even construct it with
    references to existing vectors.
-   Test construction from references in the test
-   Fixes the static_assert in the test that shouldn't really have compiled
    before

Merge branch 'bugfix/fix-vbvectortest' into 'master'

ref:core/dune-istl Formerly, this would throw an exception if

DUNE_ISTL_WITH_CHECKING

is enabled since you must not call a create iterator on an initialized
VariableBlockVector.

That being said, maybe it's a good idea to enable these checks in the CI
system.

A simple implementation for the SuiteSparse CHOLMOD solver for real valued
(double) linear systems.
Ignore dof's are supported.
The user has to take care of the correct size of
vectors in the "apply" method.

Merge branch 'make-createiterator-an-output-iterator' into 'master'

ref:core/dune-istl The class VariableBlockVector::CreateIterator behaves
basically like an STL output iterator, but it didn't quite implement the
required interface. This patch adds the missing methods and extends the unit
test.

The main benefit of this (besides interface beauty) is that you can now use
std::fill etc. to set the block sizes of a VariableBlockVector.
