  SVN rev 188278 on 2009-02-07 11:15:53Z by rwatson
  
  Merge r187814, r187820 from head to stable/7:
  
    Add a new flag to dumpfs(8), -f, which causes dumpfs to list all free
    fragments in the file system by fragment (block) number.  This new
    mode does the necessary arithmetic to generate absolute fragment
    numbers rather than than the cg-relative numbers printed in the default
    mode.
  
    If -f is passed once, contiguous fragment ranges are collapsed into
    an X-Y format as free block lists are currently printed in regular
    dumpfs output, but if specified twice, all block numbers are printed
    individually, allowing both compact and more script-friendly
    representation.
  
    This proves quite handy when attempting to recover deleted data, as it
    allows exclusion of non-deleted data from blocks searched.

    Print disk offets as %jd rather than %lld; I fixed one before committing
    but missed the other, which breaks 64-bit builds.
