This fixes FS 1292, but with my own slightly different patch.

The last commits caused compile errors for e.g. clang as I used
incomplete (only forward declared) types in template classes.
This patch moves the definition of InverseOperator and Preconditioners
from the headers solvers.hh and preconditioners into new separate
headers solver.hh and preconditioner.hh. This allows to include these
definitions in the previous headers without cause circular include directives.

This fixes FS #1224

Previously if the solver did not converge the number of iterations
that was printed and stored was one higher than the actual value.

With OpenMPI there appeared cases where MPI_Comm_free
was called after MPI_Finalize. This was caused by the
destructor of OwnerOverlapCopyCommunication being called
after MPI_Finalize.
This patch moves the destruction out of the main method.
If MPI 2 functionality is available we also check whether
MPI_Finalize was called before freeing the communicator and
only call free if not.

This patch introduces shared_ptrs at various places,
namely for the matrix hierarchies and coarse solvers.
This allows copying an AMG and using the same matrix
hierarchies in both preconditioners. Thus one could
solve the same system for various right hand sides,
where each solve happens in a different thread.

Previously we relied on CMake's export(PACKAGE ...) function when
finding dune packages without dune-control. This is error prone
when using several instances of a dune-module (either with differing
versions or built using different options). In this case there is no
control which of the instances is used.

Now we try to guess the correct build directory, if it was not
provided with ${module}_DIR, ${module}_Root or in the
CMAKE_PREFIX_PATH. Note that when using dunecontrol ${module}_DIR will
always be set. We take the path of the current toplevel build
directory and simply substitute any occurence of the name of current
module with name of the module that we try to find. This works for
both  building in a subdirectory of the source tree
(e.g. ${module-source}/build-cmake) or in a sibling directory

For A*B^T it is necessary to have matching columns, not rows.
