this is essentially backporting all the changes made in the Sparse module up to KDE SVN revision r945600, aka changeset:

df9dfa1455


This is what is needed to make Step (in KDE/kdeedu) build.

The rest of Eigen (outside of Sparse) is unaffected except for a few trivial changes that were needed.

calling this 2.0.3, will tag if no problem.
