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

We are getting rid of the schema of implementing this interface and
calling self::READ_* constants, it's confusing, inconsistent, prone to
clashes and isn't really useful for non-ORM systems (which we are not)

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.

Most notably, make it not use additional DB tables to test global
filters. Instead, just pretend that the local database is not local (via
config) and "hide" local filters with a simple test-only flag in
FilterLookup.

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.

tests. Add to the Database group tests that are making DB writes (e.g.,
for log entries).

I'm planning to add support for bypass and regex-based blocking which

it can't run if CheckUser is not installed.

This method actually consists of two: add derived vars, and initialize
content vars. The former part depends on no parameters of this method.
On the other hand, the latter part combines multiple implementations
for some of the content variables using branching.
The branching is a dirty workaround and inferior to the GRASP principle:
"When related alternatives or behaviors vary by type, assign
responsibility for the behavior to the types for which the behavior
varies."
In other words, the callers (extensions) should be responsible for
choosing the initialization strategy themselves, instead of letting
VariableGenerator figure it out.
As the first step, split the former part to a separate method.
For now, it will be implicitly called by ::addEditVars.

Service wiring should only depend on config, not on request state.
Creating a session object during service wiring causes issues with entry
points such as opensearch_desc.php that disable the session.

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.

The method for old_links retrieval depends on the "forFilter"
value, which we know in advance. If it's true, old_links should
be retrieved from the database. Make a case in the switch
that does nothing but retrieves links from the database,
and direct the evaluation to it.
This change was split from I3628a56e5 to make its review easier.
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.
