Remove doc/comm as it is now part of dune-common Somehow the deletion of doc/comm got lost while resolving a tree conflict

The index sets themselves are already there.

Step 2: removing files from dune-istl

xlc is complaining about a number of typename and template keywords in dune/istl/graph.hh. At the moment g++ parses this code without the corrections. However, as it is good C++ to add them I propose to include the applied patch.

Improved it such that placement new is only called when necessary.

Previously the two vectors are allocated in
the first call to apply. These got resused in subsequent calls to apply
and are deallocated in the destructor. Using the new mode these vectors are allocated
at the beginning and deallocated at the end of each apply method. This allows
using the same instance of superlu from different threads.

Patch provided by Arne Morten Kvarving. I just added some more
documemtation and a missing initialization.

Shouldn't subversion prevent such a thing? I even could
not use svn merge to restall the changes of r1739. 
Really weired.

This solver allows the preconditioner
to between iterations or even be nonlinear.
