Fix a memory corruption bug.

When allocating the adb_t in audiodb_open(), zero the memory; then we're
not going to try to free() or delete some arbitrary uninitialized thing
if the thing that we're opening turns out not to be an audiodb database.

#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);
}
