Clean up download code:

- move filename generation parts and related code out of DownloadManager
  download_util is not the best place for it, but it's better than
  DownloadManager which we're trying to minimize

- clean up posting tasks to different threads. There's no need to create
  separate methods for that, it was cluttering the file needlessly

- other minor cleanups, like using static_cast instead of C-style cast
