* Fix attachments getting processed despite failing content-type validation
* Add a restrictive ImageMagick security policy tailored for Mastodon
* Fix misdetection of MP3 files with large cover art
* Reject unprocessable audio/video files instead of keeping them unchanged
* Switch from unmaintained paperclip to kt-paperclip
* Drop some compatibility monkey-patches not required by kt-paperclip
* Drop media spoof check monkey-patching
It's broken with kt-paperclip and hopefully it won't be needed anymore
* Fix regression introduced by paperclip 6.1.0
* Do not rely on pathname to call FastImage
* Add test for ogg vorbis file with cover art
* Add audio/vorbis to the accepted content-types
This seems erroneous as this would be the content-type for a vorbis stream
without an ogg container, but that's what the `marcel` gem outputs, so…
* Restore missing for_as_default method
* Refactor Attachmentable concern and delay Paperclip's content-type spoof check
Check for content-type spoofing *after* setting the extension ourselves, this
fixes a regression with kt-paperclip's validations being more strict than
paperclip 6.0.0 and rejecting some Pleroma uploads because of unknown
extensions.
* Please CodeClimate
* Add audio/vorbis to the unreliable set
It doesn't correspond to a file format and thus has no extension associated.

This replace calls of String#match? with rails Regex#match?
This follows the same idea used to keep Rails 5.2 compatible with Ruby
2.2.2 in https://github.com/rails/rails/pull/32973
While this isn't exactly *wrong*, files uploaded with a “.jpe” extension will
keep that extension, which will often cause them to be served with an
incorrect mimetype.
