Add the lseek SEEK_DATA/SEEK_HOLE support into xfs_io.
The result from the lseek() call will be printed to the output.
For example:

xfs_io>  seek -h 609k
HOLE    630784

  version 7 or 8 - Eric what number is this?

Go for 13, for luck!

I think this looks ok, I won't torture you any longer.  If there's
to fix up when it really gets used in earnest we can do it then.

(it crossed my mind that for the "-r" and "-a" invocations it might be
good to print
out the offset which was sent for each SEEK_* "whence," but *shrug*)

Thanks for all the iterations,

Rich, hold off on commit, I can quickly add the whence. We can see how
she sails.
