Some exposed variables (eg. `user_ip`) used in filters are sensitive
and need to only be available to restricted groups of users.
Back-end changes:
- Add `AbuseFilterProtectedVariables` which defines what variables are
protected by the new right `abusefilter-access-protected-vars`
- Add the concept of a `protected` variable, the use of which will
denote the entire filter as protected via a flag on `af_hidden`
New UX features:
- Display changes to the protected status of filters on history and diff
pages
- Check for protected variables and the right to see them in filter
validation and don't allow a filter to be saved if it uses a variable
that the user doesn't have access to
- Check for the right to view protected variables before allowing access
and edits to existing filters that use them

Protected variables will cause the filter using them to become
protected as well. `af_hidden` can be used to track this flag,
as it is a TINYINT and can be converted into a bitmask with no
schema changes.
This is not a backwards-compatible change, as now all checks must
check the `hidden` flag specifically or otherwise will be cast to
true if any flag is set.
To support this change:
- "hidden" is considered a flag set in the `af_hidden`. This is a
change in concept with no need for updates to the column values,
as there is currently only one flag in the bitmask.
- `Flag`s store the bitmask as well as the state of single flags
and can return either.
- Any checks against the `af_hidden` value no longer check a
boolean value and instead now check the `hidden` flag value.

After temporary accounts are enabled, filters that rely on an ip
in the `user_name` will fail (eg. `ip_in_range` and `ip_in_ranges`).
To keep these filters working:
- Expose the IP through another variable, `user_unnamed_ip`, that can be
used instead of `user_name`.
- The variable is scoped to only reveal the IPs of temporary accounts
and un-logged in users.
- Wikis that don't have temporary accounts enabled will be able to see
this variable but it won't provide information that `user_name`
wasn't already providing
- Introduce the concept of transforming variable values before writing
to the blob store and after retrieval, as IPs need to be deleted from
the logs eventually and can't be stored as-is in the amend-only blob
store

Why:
- Temp accounts will be enabled by default in CI, eventually. For tests
that verify anonymous user editing behavior, we need to disable the
temp user feature
What:
- Check if the user identity isn't registered, and if so, disable auto
creating a temp user

Why:
- We want AbuseFilter to able to require a CAPTCHA if an action
matches conditions in an AbuseFilter
What:
- Implement the ConfirmEditTriggersCaptcha hook, and check to see if
the CaptchaConsequence set a global flag that indicates if we
should show a CAPTCHA

The following sniffs are failing and were disabled:
* MediaWiki.Commenting.FunctionComment.MissingDocumentationPublic
Change-Id: I6075c76d53a899aac56af027f9a956a6b9e6a667
Why:
* An AbuseFilter variable is needed that allows filters to determine
what type the current user is. That is, whether the user is an
IP address, temporary account, named user or external user.
* Currently filters implement this by inspecting the value in
the 'user_name' variable, but this is likely to break when
temporary accounts are enabled as IPs would be hidden.
* Giving a dedicated variable that indicates the type of the user
allows filters to work out this information without having to
know the specific username of the user before performing the
check.
What:
* Add the 'user_type' variable which is lazily computed. It can have
the value 'named', 'temp', 'ip' or 'external' depending on the
type of the user. If the user does not match any of these, then
the value is 'unknown'.
* Replace call to deprecated User::newFromIdentity with a use of the
UserFactory service that is dependency injected.
* Add and update tests to ensure consistent test coverage.

This patch solves a pending TODO which is to remove the ::factory()
method from the AutoPromoteGroupsHandler class. If the cache instance
is injected, we'll use it otherwise we'll default to a HashBagOStuff.
Bug: T358346
Change-Id: I2bc414da8733431d1d11025e954282fc7c73aa80
Why:
* In f3c87749b8, the sending of logs
to CheckUser when using a temporary account was fixed. As part
of that change, it was suggested to add a test to verify that
the call to `Hooks::updateCheckUserData` actually causes an
insert into the relevant CheckUser result table.
* This change adds this test as a follow-up.
What:
* Create a test for the AbuseLogger that verifies that an event is
sent to CheckUser and is saved into the DB for an abuse filter
hit. This test is only run if the CheckUser extension is installed.
Bug: T358632
Change-Id: I33ed0810db13e38eacf4e682eb54d4ffcd583084
Why:
* When CheckUser asks the AbuseFilter extension for modifications
to rows inserted into the CheckUser tables, the AbuseFilter
extension attempts to get the Filter user via User::newSystemUser
* User::newSystemUser can deadlock if multiple requests to create
the system user are being made at once.
* The CheckUserHander does not need to create the abuse filter system
and instead only needs to know if a given $user is the equal to
the FilterUser.
* As such the FilterUser service needs to provide a way to check if
a given $user is equal without creating the FilterUser.
What:
* Add FilterUser::isUserSameAs which returns a boolean value
indicating whether the Abuse Filter system user is the equal
to a given UserIdentity in the same way that UserIdentity::equals
is implemented.
* Refactor ::getUser to get the username for the filter user in
a separate method, so that the ::isUserSameAs method can also
use this method. Name this new method ::getFilterUserName.
* Add a test for the FilterUser service to ensure consistent test
coverage
* Convert the @covers and @coversDefaultClass annotations to be
a @covers for the class. This is because PHPUnit recommends this in
https://docs.phpunit.de/en/9.6/annotations.html#appendixes-annotations-covers-tables-annotations
