Update to DUNE v2.6

Description

DUNE Core v2.6 has been released. UG and PDELab received similar updates.

We should update to them asap.

Expected Adaptations

  • ReferenceElement had a major overhaul. It is now constructable with referenceElement(geometry).

  • Layouts for MultipleCodimMultipleGeomTypeMapper are deprecated.

  • This sounds really useful (for KnoFu?):

    The new method MCMGMapper::indices(entity) returns an iterable range (instance of IntegralRange<Index>) with the indices of dofs attached to the given entity: for (const auto& i : mapper.indices(entity) ) dof = vector[i];

  • StructuredGridFactory returns a unique_ptr to the grid now

  • PDELab extracts the "natural" blocking size from the function space now. This will break un-squaring in adaptivity.hh

  • L2 operator now sets integration order by itself (is probably used in adaptivity)

  • Rename namespaces this time: Dune::PDELab::istl -> Dune::PDELab::ISTL

How to test the implementation?

  • Pipeline passing
