begin pushing an adb_query_spec_t * all the way through query.

Almost all of the query specification data is in there now; missing are
the key list refinement and the query datum.

Mostly eliminate uses of the audioDB::sequenceLength member variable
throughout query.cpp.  It's still used in functions in index.cpp,
though, so make sure that a correct value is installed before calling
audioDB::index_query_loop()
