FIX: Handle nil values in DistributedCache#defer_get_set (stable) (#15980)
Themes often cache `nil` values in a DistributedCache. This bug meant that we were re-calculating some values on every request, AND triggering message-bus publishing on every request.

This fix should provide a significant performance improvement for busy sites.

FIX: Only block domains at the final destination (#15689) (#15783)
In an earlier PR, we decided that we only want to block a domain if 
the blocked domain in the SiteSetting is the final destination (/t/59305). That 
PR used `FinalDestination#get`. `resolve` however is used several places
 but blocks domains along the redirect chain when certain options are provided.

This commit changes the default options for `resolve` to not do that. Existing
users of `FinalDestination#resolve` are
- `Oneboxer#external_onebox`
- our onebox helper `fetch_html_doc`, which is used in amazon, standard embed 
and youtube
  - these folks already go through `Oneboxer#external_onebox` which already
  blocks correctly

FIX: origins_to_regexes should always return an array (#15589)
If the SiteSetting `allowed_onebox_iframes` contains a value of `*`, it will use the values of `all_iframe_origins` during the Oneboxing process. If `all_iframe_origins` itself contains a value of `*`, `origins_to_regexes` will try to return a "catch-all" regex.

Other code assumes `origins_to_regexes`will return an array, so this change ensures the `*` case will return an array containing only the catch-all regex.

DEV: Add polymorphic bookmarkable columns (#15454)
We are planning on attaching bookmarks to more and
more other models, so it makes sense to make a polymorphic
relationship to handle this. This commit adds the new
columns and backfills them in the bookmark table, and
makes sure that any new bookmark changes fill in the columns
via DB triggers.

This way we can gradually change the frontend and backend
to use these new columns, and eventually delete the
old post_id and for_topic columns in `bookmarks`.

FEATURE: Scheduled group email credential problem check (#15396)
This commit adds a check that runs regularly as per
2d68e5d942 which tests the
credentials of groups with SMTP or IMAP enabled. If any issues
are found with those credentials a high priority problem is added to the
admin dashboard.

This commit also formats the admin dashboard differently if
there are high priority problems, bringing them to the top of
the list and highlighting them.

The problem will be cleared if the issue is fixed before the next
problem check, or if the group's settings are updated with a valid
credential.

DEV: Introduce Auth::Result API for overrides_* (#15378)
This allows authenticators to instruct the Auth::Result to override attributes without using the general site settings. This provides an easy migration path for auth plugins which offer their own "overrides email", "overrides username" or "overrides name" settings. With this new api, they can set `overrides_*` on the result object, and the attribute will be overriden regardless of the general site setting.

ManagedAuthenticator is updated to use this new API. Plugins which consume ManagedAuthenticator will instantly take advantage of this change.

FIX: Blurry onebox favicon images (#15258)
This is a fix to address blurry onebox favicon images if the site you
are linking to happens to have a favicon.ico file that contains multiple
images.

This fix detects of we are trying to create an upload for a favicon.ico
file. We then convert it to a png and not a jpeg like we were doing. We
want a png because it will preserve transparency, otherwise if we
convert it to a jpeg we lose that and it looks bad on dark themed sites.

This fix also addresses the fact that .ico files can include multiple
images. The blurry images we were producing was caused by the
ImageMagick `-flatten` option when the .ico file had multiple images
which then squishes them all together. So for .ico files we are no
longer flattening them and instead we are grabbing the last image in the
.ico bundle and converting that single image to a png.

FIX: References header leading to broken email threading (#15206)
Since 3b13f1146b the email threading
in mail clients has been broken, because the random suffix meant
that the References header would always be different for non-group
SMTP email notifications sent out.

This commit fixes the issue by always using the "canonical" topic
reference ID inside the References header in the format:

topic/TOPIC_ID@HOST

Which was the old format. We also add the References header to
notifications sent for the first post arriving, so the threading
works for subsequent emails. The Message-ID header is still random
as per the previous change.

FIX: Add random suffix to outbound Message-ID for email (#15179)
Currently the Message-IDs we send out for outbound email
are not unique; for a post they look like:

topic/TOPIC_ID/POST_ID@HOST

And for a topic they look like:

topic/TOPIC_ID@HOST

This commit changes the outbound Message-IDs to also have
a random suffix before the host, so the new format is
like this:

topic/TOPIC_ID/POST_ID.RANDOM_SUFFIX@HOST

Or:

topic/TOPIC_ID.RANDOM_SUFFIX@HOST

This should help with email deliverability. This change
is backwards-compatible, the old Message-ID format will
still be recognized in the mail receiver flow, so people
will still be able to reply using Message-IDs, In-Reply-To,
and References headers that have already been sent.

This commit also refactors Message-ID related logic
to a central location, and adds judicious amounts of
tests and documentation.

FEATURE: Replace Crawl-delay directive with proper rate limiting (#15131)
We have a couple of site setting, `slow_down_crawler_user_agents` and `slow_down_crawler_rate`, that are meant to allow site owners to signal to specific crawlers that they're crawling the site too aggressively and that they should slow down.

When a crawler is added to the `slow_down_crawler_user_agents` setting, Discourse currently adds a `Crawl-delay` directive for that crawler in `/robots.txt`. Unfortunately, many crawlers don't support the `Crawl-delay` directive in `/robots.txt` which leaves the site owners no options if a crawler is crawling the site too aggressively.

This PR replaces the `Crawl-delay` directive with proper rate limiting for crawlers added to the `slow_down_crawler_user_agents` list. On every request made by a non-logged in user, Discourse will check the User Agent string and if it contains one of the values of the `slow_down_crawler_user_agents` list, Discourse will only allow 1 request every N seconds for that User Agent (N is the value of the `slow_down_crawler_rate` setting) and the rest of requests made within the same interval will get a 429 response. 

The `slow_down_crawler_user_agents` setting becomes quite dangerous with this PR since it could rate limit lots if not all of anonymous traffic if the setting is not used appropriately. So to protect against this scenario, we've added a couple of new validations to the setting when it's changed:

1) each value added to setting must 3 characters or longer
2) each value cannot be a substring of tokens found in popular browser User Agent. The current list of prohibited values is: apple, windows, linux, ubuntu, gecko, firefox, chrome, safari, applewebkit, webkit, mozilla, macintosh, khtml, intel, osx, os x, iphone, ipad and mac.

FIX: Ensure CORS rules exist for S3 using rake task (#14802)
This commit introduces a new s3:ensure_cors_rules rake task
that is run as a prerequisite to s3:upload_assets. This rake
task calls out to the S3CorsRulesets class to ensure that
the 3 relevant sets of CORS rules are applied, depending on
site settings:

* assets
* direct S3 backups
* direct S3 uploads

This works for both Global S3 settings and Database S3 settings
(the latter set directly via SiteSetting).

As it is, only one rule can be applied, which is generally
the assets rule as it is called first. This commit changes
the ensure_cors! method to be able to apply new rules as
well as the existing ones.

This commit also slightly changes the existing rules to cover
direct S3 uploads via uppy, especially multipart, which requires
some more headers.

PERF: Revert all inboxes from messages route. (#14445)
The all inboxes was introduced in
016efeadf6 but we decided to roll it back
for performance reasons. The main performance challenge here is that PG
has to basically loop through all the PMs that a user is allowed to view
before being able to order by `Topic#bumped_at`. The all inboxes was not
planned as part of the new/unread filter so we've decided not to tackle
the performance issue for the upcoming release.

FEATURE: Humanize file size error messages (#14398)
The file size error messages for max_image_size_kb and
max_attachment_size_kb are shown to the user in the KB
format, regardless of how large the limit is. Since we
are going to support uploading much larger files soon,
this KB-based limit soon becomes unfriendly to the end
user.

For example, if the max attachment size is set to 512000
KB, this is what the user sees:

> Sorry, the file you are trying to upload is too big (maximum
size is 512000KB)

This makes the user do math. In almost all file explorers that
a regular user would be familiar width, the file size is shown
in a format based on the maximum increment (e.g. KB, MB, GB).

This commit changes the behaviour to output a humanized file size
instead of the raw KB. For the above example, it would now say:

> Sorry, the file you are trying to upload is too big (maximum
size is 512 MB)

This humanization also handles decimals, e.g. 1536KB = 1.5 MB

FEATURE: Go to last unread for topic-level bookmark links (#14396)
Instead of going to the OP of the topic for topic-level bookmarks
(which are bookmarks where for_topic is true) when clicking on the
bookmark in the quick access menu or on the user bookmark list,
this commit takes the user to the last unread post in
the topic instead. This should be generally more useful than landing
on the unchanging OP.

To make this work nicely, I needed to add the last_read_post_number to
the BookmarkQuery based on the TopicUser association. It should not add
too much extra weight to the query, because it is limited to the user
that we are fetching bookmarks for.

Also fixed an issue where the bookmark serializer highest_post_number was
not taking into account whether the user was staff, which is when we
should use highest_staff_post_number instead.

FEATURE: Topic-level bookmarks (#14353)
Allows creating a bookmark with the `for_topic` flag introduced in d1d2298a4c set to true. This happens when clicking on the Bookmark button in the topic footer when no other posts are bookmarked. In a later PR, when clicking on these topic-level bookmarks the user will be taken to the last unread post in the topic, not the OP. Only the OP can have a topic level bookmark, and users can also make a post-level bookmark on the OP of the topic.

I had to do some pretty heavy refactors because most of the bookmark code in the JS topics controller was centred around instances of Post JS models, but the topic level bookmark is not centred around a post. Some refactors were just for readability as well.

Also removes some missed reminderType code from the purge in 41e19adb0d

PERF: Improve query performance all inbox private messages. (#14304)
First reported in https://meta.discourse.org/t/-/202482/19

There are two optimizations being applied here:

1. Fetch a user's group ids in a seperate query instead of including it
   as a sub-query. When I tried a subquery, the query plan becomes very
inefficient.

1. Join against the `topic_allowed_users` and `topic_allowed_groups`
   table instead of doing an IN against a subquery where we UNION the
`topic_id`s from the two tables. From my profiling, this enables PG to
do a backwards index scan on the `index_topics_on_timestamps_private`
index.

This commit fixes a bug where listing all messages was incorrectly
excluding topics if a topic has been archived by a group even if the
user did not belong to the group.

This commit also fixes another bug where dismissing private messages
selectively was subjected to the default limit of 30.

don't need to remember to update both columns if the bookmarked
post moves to another topic.

FIX: Do not send emails to mailing_list_mode subscribers for PMs (#14159)
This bug was introduced by f66007ec83.

In PostJobsEnqueuer we previously did not fire the after_post_create
event and after_topic_create event for private message topics. This was
changed in the above commit in order to publish message bus messages
for topic tracking state updates. Unfortunately this caused the
NotifyMailingListSubscribers job to be enqueued for all posts including
private messages, and admins and the users involved in the PMs got
emailed the contents of the PMs if they had mailing list mode enabled.

Luckily the impact of this was mitigated by a Guardian#can_see? check
for each mailing list mode user in the NotifyMailingListSubscribers job.
We never want to notify mailing list mode subscribers for private messages
so an early return has been added there, plus the logic in PostJobsEnqueuer
has been fixed, and tests have been added to that class where there were
none before.

`FinalDestination` now returns the `content_type` of a resolved URL.

`Oneboxer` passes this value to `Onebox` itself. Onebox engines can now specify a `matches_content_type` regex of content_types that the engine can handle, regardless of the URL.

`ImageOnebox` will match URLs with a content type of `image/png`, `jpg`, `gif`, `bmp`, `tif`, etc.
