FIX: add short_path to upload_serializer (#9417)
What problem I am trying to solve?

When an encrypted message is crafted and the image is added - discourse needs a hard refresh to display that image.

What is happening?

Everything starts here - when the upload is finished we add serialized object to the cache https://github.com/discourse/discourse/blob/master/app/assets/javascripts/discourse/components/composer-editor.js#L748:L757

Then, `discourse-encrypt` is trying to get an image from the cache and use `short_path` property
https://github.com/discourse/discourse-encrypt/blob/master/assets/javascripts/discourse/initializers/hook-decrypt-post.js.es6#L142:L143

Why is it working after a hard refresh?

After refresh, we populate cache once again using that function: https://github.com/discourse/discourse/blob/master/app/assets/javascripts/pretty-text/upload-short-url.js#L11:L17

And lookup_urls method from backend is returning `short_path`
https://github.com/discourse/discourse/blob/master/app/controllers/uploads_controller.rb#L55:L64

TL;DR We should expose short path in upload serializer. I ensured that this serializer is used only when attachments are uploaded so it should not affect performance.

FEATURE: Secure media allowing duplicated uploads with category-level privacy and post-based access rules (#8664)
### General Changes and Duplication

* We now consider a post `with_secure_media?` if it is in a read-restricted category.
* When uploading we now set an upload's secure status straight away.
* When uploading if `SiteSetting.secure_media` is enabled, we do not check to see if the upload already exists using the `sha1` digest of the upload. The `sha1` column of the upload is filled with a `SecureRandom.hex(20)` value which is the same length as `Upload::SHA1_LENGTH`. The `original_sha1` column is filled with the _real_ sha1 digest of the file. 
* Whether an upload `should_be_secure?` is now determined by whether the `access_control_post` is `with_secure_media?` (if there is no access control post then we leave the secure status as is).
* When serializing the upload, we now cook the URL if the upload is secure. This is so it shows up correctly in the composer preview, because we set secure status on upload.

### Viewing Secure Media

* The secure-media-upload URL will take the post that the upload is attached to into account via `Guardian.can_see?` for access permissions
* If there is no `access_control_post` then we just deliver the media. This should be a rare occurrance and shouldn't cause issues as the `access_control_post` is set when `link_post_uploads` is called via `CookedPostProcessor`

### Removed

We no longer do any of these because we do not reuse uploads by sha1 if secure media is enabled.

* We no longer have a way to prevent cross-posting of a secure upload from a private context to a public context.
* We no longer have to set `secure: false` for uploads when uploading for a theme component.

30990006a9 DEV: enable frozen string literal on all files
This reduces chances of errors where consumers of strings mutate inputs
and reduces memory usage of the app.

Test suite passes now, but there may be some stuff left, so we will run
a few sites on a branch prior to merging

9ab1fb7dfc FEATURE: correctly store width and height on uploads
Previously we used width and height for thumbnails, new code ensures

1. We auto correct width and height
2. We added extra columns for thumbnail_width and height, this is determined
 by actual upload and no longer passed in as a side effect
3. Optimized Image now stores filesize which can be used for analysis, decisions

Also

- fixes Android image manifest as a side effect
- fixes issue where a thumbnail generated that is smaller than the upload is no longer used
