port back: 0.4.10-dev-615-g45fd48bd0f[CDFS_NEW] -> [CDFS] No old driver, thus no new driver 0.4.10-dev-614-g5795254933[CDFS] Delete the old CDFS driver. The new MS PL licensed one worked for several years fine for us now even in the older releases. So no need to keep our old unfinished one any longer within the release-branches. They are no mausoleum. This does *not* change, which driver is actually in use. We do continue to use 1:1 the state of current releases/0.4.10
