description:
Make linear algebra backend dynamic. It should now be possible to
choose the default linear algebra backend (for Vector and Matrix)
by

  dolfin_set("linear algebra backend", "PETSc");

both in C++ and Python.

Valid options are uBLAS, PETSc, Epetra.

The default is still PETSc if available, otherwise uBLAS.
