Merge branch 'feature/cmake-allow-more-generation-dependencies' into 'master'

ref:dominic/dune-perftool I have the use case of a boundary condition file,
whose changes should retrigger the code generation process.

Merge branch 'feature/use-different-dof-numbers-for-cg' into 'master'

ref:dominic/dune-perftool I'm not 100% sure this gives the right number of
dofs for parallel applications, but at least for serial applications it is
correct.

Merge branch 'feature/sum-factorization-gmsh-files' into 'master'

ref:dominic/dune-perftool On unstructured grids we need to make sure that the
quadrature points on intersections on neighboring cells are visited in the
same order. This is done using edge consistent grids and by constructing the
geometry mappings in the right way.

Still missing:

-   Vectorization
-   Make UG grids edge consistent without writing and reading a gmsh file

I have the use case of a boundary condition file, whose changes should retrigger
the code generation process.

This options enables to generate jacobian apply methods regardless
of the `matrix_free` option. If `matrix_free` is set to true,
`generate_jacobian_apply` is also set to true. This option replaces
`matrix_free` in all contexts except in the selection of the solver.
