Factor out some bits of audiodb_query_spec_qpointers()

New functions audiodb_track_id_datum() and audiodb_datum_qpointers()
will be useful in places where audioDB::init_track_aux_data is currently
being called.  We should be able to simplify audioDB::query_loop_points
quite a lot this way...

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

int audiodb_power(adb_t *adb) {
  if(!(adb->flags & O_RDWR)) {
    return 1;
  }
  if(adb->header->length > 0) {
    return 1;
  }

  adb->header->flags |= O2_FLAG_POWER;
  return audiodb_sync_header(adb);
}
