attempt to support new and old style relocation maps,
bigger disks, correct code to write disklabels

fix relocate (I think) and correct, add command to clear corrections,
don't preserve user- and verify-detected flaws on reformat; *don't* pass
structures back and forth incessantly

get rid of private blk* routines, use (faster) libc versions

working again, I think

header file changes (guess this works, noone's complained)

move vdtimeout from kernel header
