Log Message:
Hagen Boehms cache patch broke RAWhoisClient::getSet for all objects but
RSSets and ASSets, which are also getting served by this function (so that
eg "peval -compressed fltr-bogons" no longer worked).
Revert the change to RAWhoisClient::getSet; introduce RAWhoisClient::getASSet
for ASSets and RSSets and use that in RAWhoisClient::expandASSet and
RAWhoisClient::expandRSSet
