Sketch out a "query state" structure.

As yet it's completely unused, but the intention is that accumulated
state will be collected into one of these structures for each query, and
then passed around, to help reduce the need for silly arglists.  It's
possible that this structure will also grow a pointer to the adb itself,
and be the thing passed to the LSH callback; we'll see how that
develops.
