Subject: Inet: Remove the SackRange and its use

This patch aims to simplify the use of the Range class before
introducing a more elaborate AddrRegion to replace the AddrRange. The
SackRange is the only use of the range class besides address ranges,
and the removal of this use makes for an easier modification of the
range class.

The functionlity that is removed with this patch is not used anywhere
throughout the code base.
