/register response.

GitHub sends two almost identical payloads when a pull
request is reviewed, which results in two duplicative
notification messages.
The payloads have different "action" value, with one
having the "submitted" action, whereas the other is
"edited" and has an empty "changes" dict.
We now ignore the payload with the "edited" action type
and an empty "changes" dict.
Fixes#26145.

(cherry picked from commit b5c63cfb85)
Providing a signed Camo URL for arbitrary URLs opened the server up to
being an open redirector. Return 403 if the URL is not a user upload,
and the backend image if it is. Since we do not have ImageAttachment
rows for uploads at a time we wrote `/thumbnail?` URLs, return the
full-size content.
47683144ff switched the web client to prefer the 840x560 size, as the
mobile apps prefer; remove the now-unused 300x200 size. No client was
using the generated `.jpg` formats, as all clients support `.webp`, so
remove the unused `.jpg` thumbnail as well.
Modern browsers respect the EXIF orientation information of images,
applying rotation and/or mirroring as specified in those tags. The
the `width="..."` and `height="..."` tags are to size the image
_after_ applying those orientation transformations.
The `.width` and `.height` properties of libvips' images are _before_
any transformations are applied. Since we intend to use these to hint
to rendering clients the size that the image should be _rendered at_,
change to storing (and providing to clients) the dimensions of the
rendered image, not the stored bytes.
If the email subject is something like `Fwd:`, it gets stripped to an
empty string, activating the "(no topic)" override. This however leads
to failure if the organization enables the setting forcing every message
to have a topic. Such emails should still go through, so we should just
change the topic value used.
This allows clients to potentially lay out the thumbnails more
intelligently, or to provide a better "progressive-load" experience
when enlarging the thumbnail.
Previously animated images were automatically played in the
message feed of the web app.
Now that we have still thumbnails available for them, we can add a new
personal setting, "web_animate_image_previews", which controls how the
animated images would be played in the web app message feed -- always
played, on hover, or only in the image viewer.
Fixes#31016.
In 'fetch_initial_state_data' we were doing one database query
per announcement stream.
This commit updates the logic to prefetch those streams using
select_related hence avoiding the extra db queries.
Fixes#28909.
The libvips cache is 100MB, 100 operations, or 100 files, whichever is
less. A single Django process or worker is extremely unlikely to ever
see the same image twice, much less within those timeframes.
Disable the cache, since it is mostly useless memory usage for our use
case.
The emoji dir is present in the data from our export tool. This was
added in 468afe4840.
This comment hasn't been updated since
c4b886d8ae, so probably we just forgot to
refresh it when custom emoji export was added.
Fixes warnings like “ResourceWarning: unclosed file <_io.FileIO

Previously, if someone changed the font-size or line height
settings to some value other than the legacy values, we set
dense_mode to False if it was True. This commit changes the
code to require clients to pass dense_mode as False in such
cases and raise an error otherwise.
We should flush the cache after commiting changes to DB to
make sure that the cache does not contain stale data when
updating multiple settings in a single request.
