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()

#include "audioDB.h"
extern "C" {
#include "audioDB_API.h"
#include "audioDB-internals.h"
}

void audiodb_close(adb_t *adb) {
  free(adb->path);
  free(adb->header);
  delete adb->keys;
  delete adb->track_lengths;
  close(adb->fd);
  free(adb);
}
