OpenZFS 640 - number_to_scaled_string is duplicated in several commands 

Porting Notes:
- The OpenZFS patch added nicenum_scale() and nicenum() to a
  library not used by ZFS.  Rather than pull in a new dependency
  the version of nicenum in lib/libzpool/util.c was simply
  replaced with the new one.
