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.

Fix 'zdb -o' segmentation fault

Fix a regression accidentally introduced by OpenZFS 7280 in ed828c0: since
whether to accept NULL as a valid first parameter in strchr() is implementation
specific we add an additional check to avoid crashing.

-p: Display numbers in parseable (exact) values.
Also, update iostat syntax to allow the user to specify specific vdevs
to show statistics for. The three options for choosing pools/vdevs are:
Display a list of pools:
zpool iostat ... [pool ...]
Display a list of vdevs from a specific pool:
zpool iostat ... [pool vdev ...]
Display a list of vdevs from any pools:
zpool iostat ... [vdev ...]
Lastly, allow zpool command "interval" value to be floating point:
zpool iostat -v 0.5
