nntp: NEWGROUPS uses long_response

We can amortize the cost of NEWGROUPS time filtering using the
long_response API.  This lets us handle hundreds/thousands of
inboxes without monopolizing the event loop for this command.

Further speedup is possible using MiscSearch, but that requires
not-yet-done indexing changes to MiscIdx.
