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

Turns out the MediaWikiIntegrationTestCase base class comes with a
bunch of convenience methods for this. We can even remove the custom
messages because these methods already print a lot of debug info in
case of a failure.

Echo will at some point try to load the user with the given ID, and will
throw an exception if it doesn't exist. The test is currently passing
just because we're not properly cleaning DB tables, and the user with ID
1 happens to exist at that point, but it will fail with core change
Ie2f1809d.

These tests were accessing the Database, for mainly 3 reasons:
- User::newSystemUser
- Static methods in ChangeTags
- Echo's Event class
There isn't much we can do about them, so add tests to the Database
group where needed. In some cases, there are already comments that these
tests should be made unit tests once possible.

TestUser requires a DB connection, so avoid using it in database-less
tests. Add to the Database group tests that are making DB writes (e.g.,
for log entries).

The handler class uses hook interfaces from the CheckUser extension, so
it can't run if CheckUser is not installed.

Protected effectively means "public to subclasses" and should be
avoided for the same reasons as marking everything as public should
be avoided.

Unlike what the 20-year old source comments in UrlUtils.php would
have you believe, parse_url() works fine nowadays, including for
protocol-relative URLs and indeed lots of prod code uses it directly.
The class still has some convenience value for case where you need to
expand or manipulate URLs, but for the common case of extracting a part
of it, you really don't need it.

When forFilter is true and PreparedUpdate is available
(most save operations), retrieve all_links from
PreparedUpdate::getParserOutputForMetaData. Otherwise
do what was done before.
Note that this change probably leaves some dead code. It will be dealt
with later.
NOTE: this changes code potentially executed on every save operation.

Regarding array building: Instead of adding to array with
$array[] = 'foo' and then doing array_flip(), simply do
$array['foo'] = true;
Regarding tests: I originally wanted to create a unit test but I ended
up mocking so many things that it wasn't worth it and the config variable
is globaly which first we need to clean up after deployment is done.

For fixing bugs like T65632, T105325, or T264104, we will need
to update code in more than one place at once. To prevent
regressions, create an integration test which tests the whole
pipeline, from the request submission to variable evaluation.
Edits are simulated using action=edit API call because the hook
AbuseFilter uses is run from EditPage.
To increase confidence in test coverage, remove some annotations
from AbuseFilterConsequencesTest or make them less greedy.
Ideally, it would only test consequences.
This patch includes refactoring of AbuseFilterCreateAccountTestTrait
which now only inserts the user into the database if it really
should be created.
It also restores test coverage of some other classes.

List which actions were disabled, or explicitly say that no actions were
disabled if that's the case. Also avoid the word "throttle" in messages
as it may be hard to translate. Also don't suggest optimizations to the
filter conditions -- unoptimized rules have nothing to do with a filter
being throttled.

This replaces the previous pattern of callers having to use
RevisionLookup if the result was 'implicit'. Also, in some cases where
we were just hiding things if the visibility was !== true, properly
handle the implicit case by using the new method. Make the new method
return string constants rather than bool|string.
The new method also fixes some potential info leaks which happened when
the row was hidden, the user could view suppressed AbuseLog entries, but
the associated revision was also deleted and the user couldn't see it
(this shouldn't be relevant for WMF wikis since AF deletion is
oversight-level).
Also add a bunch of tests for the various cases to ensure we don't
regress again.
