Like CheckUser, AbuseFilter should also log when specific protected
logs are viewed.
- Add support for debouncing logs to reduce log spam
- Log when AbuseFilterViewExamine with protected variables available
is accessed
- Log when SpecialAbuseLog with protected variables available is
accessed
- Log when QueryAbuseLog with protected variables available is accessed

Similar to how CheckUser logs access to IP information about temporary
accounts, AbuseFilter needs to log whenever protected variables are
accessed.
- Implement ProtectedVarsAccessLogger which handles access logging
- Log whenever a user changes their ability to access protected
variables via Special:Preferences

Users need to enable a preference before gaining access to the IPs
from `user_unnamed_ip`, a protected variable.
- Add a preference that the user can check to toggle their access
- Check for the preference and the view right for logs that reveal
protected variables on:
+ AbuseFilterViewExamine
+ SpecialAbuseLog
+ QueryAbuseLog

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

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.

Change-Id: Ifffa891879e7e49d2430a0330116b34c5a03049d
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

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.

The old parser now has the correct name "Evaluator", so the
ParserFactory name was outdated. Additionally, the plan is to create a
new RuleChecker class, acting as a facade for the different
parsing-related stages (lexer, parser, evaluator, etc.), which is what
most if not all callers should use. The RuleCheckerFactory still returns
a FilterEvaluator for now.
Also, "Parser" is a specific term defining *how* things happen
internally, whereas "RuleChecker" describes *what* callers should expect
from the new class.

Remove unnecessary setters, injecting everything in the constructor.
These were leftovers from before the introduction of ParserFactory.
Remove public access to the conds used, include the information inside
the returned ParserStatus instead, and consequently simplify callers.
Change-Id: I0a30e044877c6c858af3ff73f819d5ec7c4cc769
All methods were moved to the new parser. Tests and other pieces were
adjusted to expect just a single parser. There are still some TODOs
(remove AFPTransitionBase, remove $this->mCur), but these are left for
another commit.
Note that the new parser was not renamed: this is because the names are
wrong anyway (CachingParser is more of an Evaluator than a Parser, and
AFPTreeParser is the real parser, and should be renamed as well).
NOTE to reviewers: this patch looks quite big, but if you diff the old
parser with the new version of the CachingParser, you'll notice that the
diff is actually small, since everything was basically copied verbatim.
