When assigning a BCRSMatrix to another BCRSMatrix which was setup for
a different size/pattern, it segfaulted and I got the following
Exception:

"InvalidStateException [allocate:.../dune/istl/bcrsmatrix.hh:2108]:
Rows have already been allocated, cannot allocate a second time."

The problem was, that inside the assignment operator the rows (r) were
never deallocated. This commit fixes this and adds a testcase.

Testcase slightly modified by Markus.

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.

 * Extended the section on the license in README

WARNING:

Currently COPYING contains the GPL without the exception. The runtime
exception is just mentioned in the README. It is  not clear to me
whether it should be included into the COPYING file. In libstdc++ it
is not included there but in all source files.

Sven: please audit the licence again.
