Access control compatibility with Friendica

[schmaker]

Pitch

Federation with Friendica works fine, but images that are not public cannot be reached from Mastodon.

Friendica issue:
https://github.com/friendica/friendica/issues/11542

Dev forum discussion:

As Friendica devs said: "We expect that the other side then uses a signed HTTP request so that the permissions can be checked. But it seems as if other systems aren't doing this."

Motivation

Everyone would benefit with enhanced federation
