Support dropping lost cluster chains (on request by Christoph Badura) While being here, fix some minor bugs, mostly with format strings
- remove fstab walking code - add missing prototypes - add missing argument in dir.c near "Truncate", where delete() was being called with fewer args. I think the missing argument should be a zero, but Wolfgang should check...
Free any data structures when finishing a check (at the latest)
Generate full pathnames only on request Minor cleanup, RCS Ids in .h files
