Merge branch 'feature/sum-factorization-on-unstructered-grids' of ssh://gitlab.dune-project.org:22022/dominic/dune-perftool into feature/sum-factorization-on-unstructered-grids

Calculate the evaluation and jacobians of geometry mappings of cells
using sum factorization. By avoiding all geometry mapping of intersections
we can avoid the face-twist problem and just make the grid consistens (not
yet done).

TODO:
- Make grid consistent
- Vectorization
- 3D

Not yet implemented:

- Vectorization of quadrature loop
- Anisotropic amount of quadrature points per direction

Merge branch 'bugfix/adapt-error-threshold' into 'master'

Now running on the Heidelberg infrastructure.

Otherwise, OpenMP thinks it is allowed to take as
many threads as there are cores, which leads to a
quadratic catastrophe when running tests in parallel.
OpenMP is used by Debian's installation of Suitesparse.

CI (no -ffast-math) produces a slightly relaxed error.

Rename the function and remove the backend switch. Reasoning:

- This function was only called once without the backend switching
  mechanism.
- The function takes different arguments than the pdelab
  pymbolic_quadrature_position.
- It returns only one component of the quadrature point.

Probably not the solution we want to have in the long run but right
now it is not possible to have a backend switch for
default/blockstructured/sumfact. This way the old code should behave
the same way as before and it is possible to switch between those
three things.

Note: This is still structured for now

The upstream bug is fixed, the workaround is not necessary anymore.
