That really was a hack: the build system should do it.

'Mixed' means that the spaces for deformations and microrotations can
be chosen separately.

At this point there hasn't been a lot of testing yet.  In particular,
parallelizing the assembly is currently not supported.

That makes it easier to keep them consistent.  Also, the code is shorter.

This used to be 'int', because dunepython didn't support the python-to-C
conversion for bool.

In particular, I can use math.cos in the initial values.

Newer versions of ADOL-C do not define 'overwrite' anymore, hence there
is no risk of macro clashing.

That way, we can now control what vertices are Dirichlet and Neumann without having
to recompile the code.

[[Imported from SVN: r9794]]

This will eventually allow to not hard-wired the Dirichlet vertices
into the C++ code, and change them without recompiling.  This also
means we can remove some preprocessor switches.

Currently, though, the Python code is still hard-wired, so we are
only half-way there.

Note that this patch may break several test problems.  I did not test
all of them.

Make its DirichletValues function a proper Dune VirtualFunction.

Prescribe Dirichlet values for the transverse director, as Neff
does it in his papers.

Christian Engwer told me a trick how to get the mpiHelper instance without
known argc and argv.
