Split YaspGrid tests into more tests and introduce parallel testing

The previous YaspGrid test was a single test which took ages to compile and run.

This branch remodels the Yasp testing suite to achieve the following:

* [x] Split the different parts into separate tests
* [x] Introduce a more sophisticated communication test
* [ ] Test periodic grids
* [x] Do parallel testing through dune_add_test
* [x] Test with -Wall -Werror!!!
* [x] Have tests with and without deprecations!

Update test environments

- No longer test with clang 3.5.
- Add clang 3.8 from Debian 8 + backports
- Add gcc 5.4 + clang 3.8 from Ubuntu 16.04 LTS.
- Use `duneci-standard-test`

Feature/deprecate external ug



See merge request !94

This (not-yet merged to master) feature of dune_add_test
allows us to halve the execution time of the yasp test suite here.

There seems to be a bug to fix.

[test] add static check for higher codimension information on grid views

Until now, the static part of the grid check only check on codim 0 structures,
e.g., on the index set. This patch also performs these checks on higher
codimensions.

For the IndexSet::subIndex method, it will only check whether the method
compiles. If codim > 0, it will silently ignore a Dune::NotImplemented
exception, so that grids are not forced to implement the method; it simply has
to compile.

Note: This check is able to detect the error fix in !86.

This merge request is basically !89 , but with Martin's initial implementation removed.
As it only lived to be completely replaced 24h later, I didn't see the point in keeping
it in the history.

Implement the subIndex method for entities of all dimensions

Previously, it was available only for elements.

The following question appears: what does the codim-parameter in

  template<int cc>
  unsigned int subIndex (const Codim<cc>::Entity& e,
                         int i,
                         unsigned int codim) const

mean?  Is it the codimension wrt to the grid, or wrt to the entity e?
I did not find this documented anywhere, and therefore made my own
choice.  The 'codim' in this patch is the codimension with respect
to the *grid*.

Various OneDGrid cleanup patches

They are already deprecated in the interface class.  Since few people
actually use the interface class, let's deprecate the methods on the
implementation class OneDGrid as well.
