Initial implementation of accumulators for forthcoming audiodb_query().

Minimally tested using a temporary test harness; do not use as food.

As well as the necessary C++ magic, doodle in API header files aiming
vaguely for a sane API.

#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);
}
