Punishment gluttony.

Continue teasing out vague orthogonalities by beginning the task of
using an adb_query_parameters_t.  This does have the benefit of making
the distance calculation clearer, and we begin to see the shape of a
putative audiodb_query() emerging from the shrapnel of audioDB::query.
(Only the general shape; the detail is still a long, long way away).

#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);
}
