MFV r325013,r325034: 640 number_to_scaled_string is duplicated in several commands

Browse Source 
illumos/illumos-gate@0a0551200e
0a0551200e

https://www.illumos.org/issues/640
  du(1), df(1m), ls(1), and swap(1m) all include a copy (it appears literally
  copied) of the 'number_to_scaled_string' function in their source. This should
  be moved to a shared library and all 4 commands should use this instead.

FreeBSD note: of all libcmdutils functionality ZFS (and other illumos
contrib code) currently uses only nicenum() function (which is similar
to humanize_number but has some formatting differences).  For this
reason I decided to not port the whole library.  As a result, nicenum.c
from libcmdutils is compiled into libzfs and libzpool.  This is a bit
ugly, but works.  If one day we are forced to create libillumos, then
the file should be moved to that library.
