Do not rely on hardcoded strings as an API for recording anonymous user file uploads in the session

The code added in https://www.drupal.org/SA-CORE-2017-003 → required writing to the session every time an anonymous user uploads a private file, and also reading from that session to check if the current anonymous user is the same one who uploaded it and should have access to it.

For simplicity in a security release, this was done using a hardcoded string and a direct write to the session. But it would be useful to have more of API for this. There were two possible suggestions related to that:

  1. @larowlan suggested replacing the string with a class constant.
  2. I suggested creating an actual API to grant/check anonymous access to the file, and putting all the session code internal to that API. I suggested this partially because we do know of at least a couple contrib modules that need to deal with this functionality also (see the https://www.drupal.org/project/drupal/releases/7.56 → release notes).

The options aren't mutually exclusive (it is possible to do both).
