YAY!

audioDB::index_query_loop is now disentangled.  Hardwired lsh_in_core to
true, and invented a new QID flag for !lsh_exact.  All tests continue to
pass.

The plans now:
- extract the audiodb_query_spec() function from inside audioDB::query,
  and move audioDB::query (and the timestamps function) to audioDB.cpp;
- write libtests/0036 and libtests/0037 in terms of audiodb_query_spec();
- rewrite all the other libtests in terms of audiodb_query_spec();
- delete audiodb_query() [ and maybe rename audiodb_query_spec(), I
  dunno];
- implement example bindings (probably to Lisp, because that's what I
  know best);
- see if anyone other than me can work out how the API works.  If not,
  provide documentation;
- revise API in the light of user feedback.
