DEV: attempt to stabilize flaky spec
Spec was checking implementation when it did not need to, temp file was blank
so optimized image should be blank

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.

Guo Xiang Tan 20e783337d DEV: Remove use of fake external store in optimized images spec.
Testing against fake stuff is bad because we're not testing against reality when
reality changes.

Sam Saffron 4ea21fa2d0 DEV: use #frozen_string_literal: true on all spec
This change both speeds up specs (less strings to allocate) and helps catch
cases where methods in Discourse are mutating inputs.

Overall we will be migrating everything to use #frozen_string_literal: true
it will take a while, but this is the first and safest move in this direction

Penar Musaraj c50db76f5d FIX: do not treat TIFF, BMP, WEBP as images
Treating TIFF and BMP as images cause us to add them to IMG tags, this is very inconsistent across browsers.

You can still upload these files they will simply not be displayed in IMG tags.

Sam 570877da3c FEATURE: store thumbnail algorithm version in optimized image table
Previously we had no idea what algorithm generated thumbnails, this starts tracking the version.

We also bumped up the version to force all optimized images to be generated. This is important cause we recently introduced pngquant which results in much smaller images.

Sam 766e67ce57 FEATURE: introduce lossy color optimization on resized pngs
This feature ensures optimized images run via pngquant, this results extreme amounts of savings for resized images. Effectively the only impact is that the color palette on small resized images is reduced to 256.

To ensure safety we only apply this optimisation to images smaller than 500k.

This commit also makes a bunch of image specs less fragile.

Robin Ward 662cfc416b FEATURE: Show a blurry preview when lazy loading images
This generates a 10x10 PNG thumbnail for each lightboxed image.
If Image Lazy Loading is enabled (IntersectionObserver API) then
we'll load the low res version when offscreen. As the image scrolls
in we'll swap it for the high res version.

We use a WeakMap to track the old image attributes. It's much less
memory than storing them as `data-*` attributes and swapping them
back and forth all the time.

Sam 0a442e319c FIX: correct svg handling for images
We regressed and optimized images no longer worked with svg

The following adds the correct logic to simply copy file for svgs
and bypasses resizing for svg avatars

Sam 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

Sam 8b5e42ea16 FIX: always test and coerce to image on upload
In the past the filename of the origin was used as the source
for the extension of the file when optimizing on upload.

We now use the actual calculated extension based on upload data.

Andy Waite 3e50313fdc Prepare for separation of RSpec helper files
Since rspec-rails 3, the default installation creates two helper files:
* `spec_helper.rb`
* `rails_helper.rb`

`spec_helper.rb` is intended as a way of running specs that do not
require Rails, whereas `rails_helper.rb` loads Rails (as Discourse's
current `spec_helper.rb` does).

For more information:

https://www.relishapp.com/rspec/rspec-rails/docs/upgrade#default-helper-files

In this commit, I've simply replaced all instances of `spec_helper` with
`rails_helper`, and renamed the original `spec_helper.rb`.

This brings the Discourse project closer to the standard usage of RSpec
in a Rails app.

At present, every spec relies on loading Rails, but there are likely
many that don't need to. In a future pull request, I hope to introduce a
separate, minimal `spec_helper.rb` which can be used in tests which
don't rely on Rails.
