[2204] cleanup: removed unused func, and renamed "ClientList" with "DataSrc".

getClientListClasses() was removed.  It's not used anymore.
a few methods named with "ClientList" were renamed with adding "DataSrc".
The resulting names are a bit long, but since there's no namespace
qualification, simply saying "client" can be confusing (it could be
interpreted to mean DNS clients, for example).
