This package is using some common utilities from
a library that used to live in the network stack.
A better home for these utilities is frameworks/libs,
so this topic moves the files ther and also changes
the package of some utilities.

See aosp/1350222 and aosp/1350182 for a detailed
description of the specific files that moved.

Do not run ethernet tethering tests if tethering is not supported
because Tethering APIs would fail. Also skip the test if
EthernetManager is not avaliable. EthernetManager would be null if
there are no FEATURE_ETHERNET and FEATURE_USB_HOST.

If the test run adb over network and ethernet is available, it is likely
that adb may run over ethernet. Then the test would fail because adb
would break when ethernet is switching from client mode to server mode.

part of several mainline modules.

Also refine comments in DhcpResults following feedback in previous
