Grouped backports to the 4.1 branch.

  • Comments: Prevent users who can not see a post from seeing comments on it.
  • Shortcodes: Restrict ajax handler for media shortcode.
  • Prevent unintended behavior when certain objects are unserialized.

Merges [56835], [56836], and [56838] to the 4.1 branch.
Props xknown, jorbin, joehoyle, peterwilsoncc, ehtis, tykoted, antpb.
