This changeset fixes a huge pile of problems, as indicated in the error log of the Doxygen run after merging all the recent Doxygen improvements unfortunately, auto-linking does still not work at various places. There is no clear indication what might be the problem. Possibly the rather unstable Sqlite support in this Doxygen version is the cause. Anyway, needs to be investigated further.
