Hey, who let audioDB::set_up_query into the room?

audioDB::set_up_query and audioDB::set_up_db both do all sorts of
horrible pointer manipulation.  Define a structure to contain all the
pointers, rather than having the hideous argument lists full of double
**, and use it in audioDB::set_up_query and
audioDB::set_up_query_from_key.  (Those two functions are desperately
close to becoming one function, incidentally, or possibly even no
functions given the existence of adb_datum_t...)

#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);
}
