Easy access to quadraturerule and referenceelement

This adds new functions `quadratureRule()` and `referenceElement()` to
reduce the amount of boiler plate code in the local operators as well as
new wrappers around `Dune::ReferenceElement` and `Dune::QuadratureRule`.
These wrappers have value semantics and can be copied around freely.

The freestanding functions are also injected into the `Dune` namespace
to enable ADL lookup. This is important to allow for forward
compatibility once the functions appear in the core modules.

Use it like this:

```c++
#include <dune/pdelab/common/singletonaccess.hh>

auto geo = eg.geometry();
auto ref_el = referenceElement(geo); // capture by value!

std::size_t quadrature_order = 4;
for (auto& ip : quadratureRule(geo,quadrature_order))
{
  // loop over points
}
```

On the second view it turned out that this test is doing the
computations on YaspGrid and UGGrid is not used at all.
So don't include UGGrid.

Adapt grid and multiple GFS with multiple vectors

Makes it possible to adapt multiple GFS with several corresponding
vectors. Implementation follows the interface suggestion from
https://gitlab.dune-project.org./pdelab/dune-pdelab/issues/37

 providing
two new user functions:

- transferSolution: Pack a GFS and corresponding vectors.
- adaptGrid: Adapt grid and all GFS and vectors from the packs.

[CMake] Do not exclude dune/pdelab/test/fem from testing

This is a leftover from the usage of the old testing magic.
Not needed as in fem pdelab_add_test is used.

Only applies to 2.4, it is already fixed in master.

Fix some problems in adaptivity code

This patch set fixes a number of issues in the adaptivity code:

- The EntitySet in the GridFunctionSpace did not properly get updated
  after adapting the grid. Both EntitySet::update() and
  GridFunctionSpace::update() now take an optional bool parameter to
  force an update.
- The adaptivity code now calls GridFunctionSpace::update() with the
  force flag enabled.
- There was a mixup between local and global id sets.
- Removed last occurences of directly using the GridView instead of the
  EntitySet within the adaptivity code.

Feature: Test for complex field type computation.

This test checks the support for computations with complex field types
by solving a complex-valued PDE with origin of practical relevance.

A broad collection of linear solvers undergo this test which are called
either directly from dune-istl or from the backends in dune-pdelab.

This test also demonstrates on how to impose Robin boundary conditions.

Improve handling of problems with complex field type

The reduction and norms should always be real-valued, but none of the
backends currently extract the real type from the field type. This patch
does at least change the interface to do so correctly.

This should always be a real value, so extract it from the field type.
