FIX: Secure upload post processing race condition (#23968)
* FIX: Secure upload post processing race condition

This commit fixes a couple of issues.

A little background -- when uploads are created in the composer
for posts, regardless of whether the upload will eventually be
marked secure or not, if secure_uploads is enabled we always mark
the upload secure at first. This is so the upload is by default
protected, regardless of post type (regular or PM) or category.

This was causing issues in some rare occasions though because
of the order of operations of our post creation and processing
pipeline. When creating a post, we enqueue a sidekiq job to
post-process the post which does various things including
converting images to lightboxes. We were also enqueuing a job
to update the secure status for all uploads in that post.

Sometimes the secure status job would run before the post process
job, marking uploads as _not secure_ in the background and changing
their ACL before the post processor ran, which meant the users
would see a broken image in their posts. This commit fixes that issue
by always running the upload security changes inline _within_ the
cooked_post_processor job.

The other issue was that the lightbox wrapper link for images in
the post would end up with a URL like this:

```
href="/secure-uploads/original/2X/4/4e1f00a40b6c952198bbdacae383ba77932fc542.jpeg"
```

Since we weren't actually using the `upload.url` to pass to
`UrlHelper.cook_url` here, we weren't converting this href to the CDN
URL if the post was not in a secure context (the UrlHelper does not
know how to convert a secure-uploads URL to a CDN one). Now we
always end up with the correct lightbox href. This was less of an issue
than the other one, since the secure-uploads URL works even when the
upload has become non-secure, but it was a good inconsistency to fix
anyway.

SECURITY: Prevent arbitrary topic custom fields from being set
Why this change?

The `PostsController#create` action allows arbitrary topic custom fields
to be set by any user that can create a topic. Without any restrictions,
this opens us up to potential security issues where plugins may be using
topic custom fields in security sensitive areas.

What does this change do?

1. This change introduces the `register_editable_topic_custom_field` plugin
API which allows plugins to register topic custom fields that are
editable either by staff users only or all users. The registered
editable topic custom fields are stored in `DiscoursePluginRegistry` and
is called by a new method `Topic#editable_custom_fields` which is then
used in the `PostsController#create` controller action. When an unpermitted custom fields is present in the `meta_data` params,
a 400 response code is returned.

2. Removes all reference to `meta_data` on a topic as it is confusing
   since we actually mean topic custom fields instead.

FIX: min_personal_message_post_length not applying to first post (#23531)
* FIX: min_personal_message_post_length not applying to first post

Due to the way PostCreator is wired, we were not applying min_personal_message_post_length
to the first post.

This meant that admins could not configure it so PMs have different
limits.

The code was already pretending that this works, but had no reliable way
of figuring out if we were dealing with a private message

FIX: Do not enqueue update_post_uploads_secure_status unnecessarily (#20366)
We call `post.update_uploads_secure_status` in both
`PostCreator` and `PostRevisor`. Only the former was checking
if `SiteSetting.secure_uploads?` was enabled, but the latter
was not. There is no need to enqueue the job
`UpdatePostUploadsSecureStatus` if secure_uploads is not
enabled for the site.

DEV: Replace #pluck_first freedom patch with AR #pick in core (#19893)
The #pluck_first freedom patch, first introduced by @danielwaterworth has served us well, and is used widely throughout both core and plugins. It seems to have been a common enough use case that Rails 6 introduced it's own method #pick with the exact same implementation. This allows us to retire the freedom patch and switch over to the built-in ActiveRecord method.

There is no replacement for #pluck_first!, but a quick search shows we are using this in a very limited capacity, and in some cases incorrectly (by assuming a nil return rather than an exception), which can quite easily be replaced with #pick plus some extra handling.

PERF: Perform only one category update when creating a new topic (#19361)
When under extremely high load, it has been observed that updating the categories table when creating a new topic can become a bottleneck.

This change will reduce the two updates to one when a new topic is created within a category, and therefore should help with performance when under extremely high load.

DEV: Rename secure_media to secure_uploads (#18376)
This commit renames all secure_media related settings to secure_uploads_* along with the associated functionality.

This is being done because "media" does not really cover it, we aren't just doing this for images and videos etc. but for all uploads in the site.

Additionally, in future we want to secure more types of uploads, and enable a kind of "mixed mode" where some uploads are secure and some are not, so keeping media in the name is just confusing.

This also keeps compatibility with the `secure-media-uploads` path, and changes new
secure URLs to be `secure-uploads`.

Deprecated settings:

* secure_media -> secure_uploads
* secure_media_allow_embed_images_in_emails -> secure_uploads_allow_embed_images_in_emails
* secure_media_max_email_embed_image_size_kb -> secure_uploads_max_email_embed_image_size_kb

It makes more sense to use user_ids for the UserCommScreener

in most cases the ID will be available, not the username. This
was discovered while starting work on a plugin that will

the extra query is negligble.

DEV: Refactor user mute/ignore/disallow PM checks into central class (#17366)
The idea behind this refactor is to centralise all of the user ignoring / muting / disallow PM checks in a single place, so they can be used consistently in core as well as for plugins like chat, while improving the main bulk of the checks to run in a single fast non-AR query.

Also fixed up the invite error when someone is muting/ignoring the user that is trying to invite them to the topic.

Breakdown of fixes in this commit:

* `UserStat#topic_count` was not updated when visibility of
the topic changed.

* `UserStat#post_count` was not updated when post was hidden or
unhidden.

* `TopicConverter` was only incrementing or decrementing the counts by 1
even if a user has multiple posts in the topic.

* The commit turns off the verbose logging by default as it is just
noise to normal users who are not debugging this problem.

FIX: Clear drafts only when post is created by real user (#15720)
This commits adds a new advance_draft to PostCreator that controls if
the draft sequence will be advanced or not. If the draft sequence is
advanced then the old drafts will be cleared. This used to happen for
posts created by plugins or through the API and cleared user drafts

FIX: Add DB constraints for post & topic counter cache for `UserStat` (#15626)
Ensures that `UserStat#post_count` and `UserStat#topic_count` does not
go below 0. When it does like it did now, we tend to have bugs in our
code since we're usually coding with the assumption that the count isn't
negative.

In order to support the constraints, our post and topic fabricators in
tests will now automatically increment the count for the respective
user's `UserStat` as well. We have to do this because our fabricators
bypasss `PostCreator` which holds the responsibility of updating `UserStat#post_count` and
`UserStat#topic_count`.

FIX: Don't publish PM archive events to acting user. (#14291)
When a user archives a personal message, they are redirected back to the
inbox and will refresh the list of the topics for the given filter.
Publishing an event to the user results in an incorrect incoming message
because the list of topics has already been refreshed.

This does mean that if a user has two tabs opened, the non-active tab
will not receive the incoming message but at this point we do not think
the technical trade-offs are worth it to support this feature. We
basically have to somehow exclude a client from an incoming message
which is not easy to do.

FEATURE: Allow durations < 1 hour and < 1 day for topic timers where duration is specified (auto delete replies, close based on last post) (#11961)
This PR allows entering a float value for topic timers e.g. 0.5 for 30 minutes when entering hours, 0.5 for 12 hours when entering days. This is achieved by adding a new column to store the duration of a topic timer in minutes instead of the ambiguous both hours and days that it could be before.

This PR has ommitted the post migration to delete the duration column in topic timers; it will be done in a subsequent PR to ensure that no data is lost if the UPDATE query to set duration_mintues fails.

I have to keep the old keyword of duration in set_or_create_topic_timer for backwards compat, will remove at a later date after plugins are updated.

This necessitated a refactor of the UploadSecurity class to provide reasons why the upload security would have changed.

As well as this, a source is now provided from the location which called for the upload's security status to be updated as they are several (e.g. post creator, topic security updater, rake tasks, manual change).

DEV: raise an exception when trying to create a post within a transaction (#11287)
Hopefully this will prevent fellow developers from spending a morning
trying to figure out why the jobs that are run after a post is created
are not finding the post in the database.

That's because if you're inside a transaction when creating a post, the jobs
will likely run before the transaction is being commited to the database.

There was a "warning" in the comments of the PostCreator class but raising an
exception should hopefully help catch those issue much faster :fingers_crossed:.

This is hard to test since all the tests are run in a transaction...

* Sometimes I will read the topic in mobile and I will prefer to reply in PC later. Or I may have to do some research before reply. So I will bookmark it for reply later.
