This ensures classes are used from the service-connectivity jar, instead
of using classes from the system_server bootclasspath when there is a
name conflict.
Any developer adding a future class should do so in a subpackage of
com.android.connectivity (such as com.android.connectivity.server).
Otherwise, jarjar rules need to be added manually until b/180995093 is
fixed.
Also update current jarjar rules so that classes are jarjared to
com.android.connectivity.[original name], making it easier to find the
original source. This is consistent with the wifi module.

dexdump on service-connectivity.jar shows no classes outside of
com.android.connectivity and com.android.server

Move the tests together with packages/Connectivity code, so both can be
moved to packages/modules/Connectivity together.
Also reorganize unit tests in a unit/ directory, as other tests
(integration/, common/ etc.) have been added in tests/net since they
were created. This makes the directory structure consistent.
