Introduce zpool_get_prop_literal interface
This change introduces zpool_get_prop_literal. It's an expanded version
of zpool_get_prop taking one additional boolean parameter. With this
parameter set to B_FALSE it will behave identically to zpool_get_prop.
Setting it to B_TRUE will return full precision numbers for the
following properties:
ZPOOL_PROP_SIZE
ZPOOL_PROP_ALLOCATED
ZPOOL_PROP_FREE
ZPOOL_PROP_FREEING
ZPOOL_PROP_EXPANDSZ
ZPOOL_PROP_ASHIFT
Also introduced is a wrapper function for zpool_get_prop making it
use zpool_get_prop_literal in the background.
