Forward-port non-security-parts of SA-CORE-2014-003 file access bypass fixes to Drupal 8

The security fixes for the file bypass access issues in SA-CORE-2014-003 → wound up being very different between Drupal 7 and Drupal 8.

In Drupal 7, there was:

The original security fix, http://cgit.drupalcode.org/drupal/commit/?id=83b80acad8431fcd56e9a331ba0... (see the file-related changes from that commit)
The followup fix to address a non-security-related regression, http://cgit.drupalcode.org/drupal/commit/?id=b90a53201d7c3ce0dc3a240d537... (see #2305017: Regression: Files or images attached to certain core and non-core entities are lost when the entity is edited and saved → )

In Drupal 8, there was:

http://cgit.drupalcode.org/drupal/commit/?id=8f3f79ad34fcdc6db7b5bbb34f0... (see #2304969: Port private files access bypass from SA-CORE-2014-003 → )

Security-wise they both work and Drupal 8 does not appear to have any functional regressions either but there are a couple things from the various Drupal 7 commits that would be good to add to Drupal 8:

Something comparable to file_download_access(), which looks like a useful API function to me for Drupal 8 too.
The tests that were added in http://cgit.drupalcode.org/drupal/commit/?id=b90a53201d7c3ce0dc3a240d537... (although the regression was never present in Drupal 8, it still would probably be good to have the tests).

Thank you for creating this issue to improve Drupal.

We are working to decide if this task is still relevant to a currently supported version of Drupal. There hasn't been any discussion here for over 8 years which suggests that this has either been implemented or is no longer relevant. Your thoughts on this will allow a decision to be made.

Since we need more information to move forward with this issue, the status is now Postponed (maintainer needs more info). If we don't receive additional information to help with the issue, it may be closed after three months.
