Make the keys std::set in adb_t a std::map instead.

The key's index can usefully be the value, and now suddenly we can
remove audioDB::getKeyPos and its oh-so-helpful "this should be an STL
map" comment.

#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);
}
