In particular, this brings stronger typing for getID(), and we can get
rid of many phan suppressions.

So everything can be loaded using PSR-4. These classes weren't renamed,
nor the alias for the AbuseFilter class was deprecated, because they
should be refactored first.

This makes VariableHolder a true value object, and introduces a
stateless service, VariableManager, to operate on it.
Note, in theory, this new service is still cyclically coupled with
LazyVariableComputed. However, it's now two stateless service being
coupled, not two smart/god value objects, so we've still earned
something. For now, the dependency is hidden by using a callback. Some
alternatives for that are mentioned in a code comment.

This is an important step towards removing the AbuseFilter class. Note:
proposals for the name of the new service are welcome.

See task for a description of the plan. Also note that
AFComputedVariable should be renamed and its properties made private.
This commit includes some adjustments for taint-check in
AbuseFilter::buildVarDumpTable and ::revisionToString.
There's some space for improvement in the new LazyVariableComputer, but
that's left for another commit.

This is the last big step towards moving Consequences-related things away from
AbuseFilterRunner. There's still some cleanup to do (+ write proper tests), but
this should really be the last important code change.

AbuseFilter emulates the storage mechanism also used for page content.
Instead of duplicating the relevant code, AbuseFilter should use the
same BlobStore service also used by RevisionStore.
Note that this change is not strictly needed to resolve T198341, but is
needed to unblock T183490

The consequence-taking logic is moved away from AbuseFilterRunner, to
dedicated classes. There's now one class per consequence, encapsulating
everything it needs to take the consequence.
Several interfaces allow customizing different types of consequences.
Every "special check" in AbuseFilter was generalized to use these
interfaces, rather than knowing how to handle each consequence.
Adding more consequences from other extensions will also be easier, and
it should happen via a hook (not a global), returning a class that
implements Consequence. The BCConsequence class was temporarily added
for legacy custom consequences.
A ConsequenceFactory class is added to instantiate consequences; this
would possibly benefit from using ObjectFactory, but it doesn't because
it would also reduce readability (although we might do that in the
future).
These classes are still not covered by unit tests, and this is left to
do for later. The new unit tests should mostly replace
AbuseFilterConsequencesTest. @covers tag were added to keep the status
quo (i.e. code that was considered covered while in AbuseFilterRunner
will still be considered covered), although we'll have to adjust them.

This is a no-op, moving code around, introducing another distinction re
"filtering actions", which now happens in 2 steps:
- The first step only uses "generic" information available by looking
at enabled actions as a "group". This includes keeping only the
longest block, and removing 'disallow' if other blocking actions are
enabled.
- The second step uses information that is only available after having
"partly executed" (named "pre-checked") a consequence. For instance,
we need to pre-check 'throttle' to see if the throttle was hit, and
remove any other actions if not.
Change-Id: I7be5cfaa61e942a06f97ed52f50e9c8c70a120e8
This way we don't have special cases in executeFilterActions, and instead, we execute
all actions in the same place. In turn, this is going to ease the
transition to a new consequences system: next step is refactoring this
code into a service with proper DI etc.

This moves a lot of things away from the AbuseFilter class. There's a
nasty static dependency on ChangeTags, but it's very limited anyway, and
it's going to be fixed once T245964 is resolved.

The current code was more of a subpar, temporary solution. However, we
need a stable solution in case more variables will be deprecated in the
future (T213006 fixes the problem for the past deprecation round). So,
instead of setting a hacky property, directly translate all variables
when loading the var dump. This is not only stable, but has a couple
micro-performance advantages:
- Calling getDeprecatedVariables happens only once when loading the
dump, and not every time a variable is accessed
- No checks are needed when retrieving a variable,
because names can always assumed to be new
Some simple benchmarks reveals a runtime reduction of 8-15% compared to
the old code (8% when it had varsVersion = 2, 15% for varsVersion = 1),
which comes at no cost together with increased readability and
stability. It ain't much, but it's honest work.

This will decouple a bit the huge and chaotic tangle of AF classes. Some
boilerplate code for AbuseFilter services is also added with this patch.
Note that this requires injecting a KeywordsManager in
AbuseFilterVariableHolder, or unit tests would fail. This is still
incomplete, and the Manager is only injected in tests, because
VariableHolder still has to be refactored.
The test for the UpdateVarDumps script had to be updated, because
serializing VHs in there was a bad choice. As pointed out in a comment,
the test is likely going to break again once we remove the BC code, but
I hope that we'll be able to remove the test at that point.

Also fix the test for _first_contributor vars to cover all variables,
use builtin methods to compute the var (rather than calling
setLazyLoadVar), and to be an integration test.

This is another step needed to reduce the size of the gigantic
AbuseFilter and AbuseFilterHooks classes. It also makes many methods
non-static, for more testability.
Note, this layout is still not final. We should somehow merge the
functionality of VariableGenerator and AFComputedVariable, for which
I already have plans.

-new_html: also strip the "Transclusion limit" comment if present, and
anyway take it into account (as well as a "</div>"), which right now
prevent the PP limit report from being stripped as well.
-new_text: trim extra whitespace on the right, which is created when
stripping the aforementioned comments.
Also simplify the test for getEditVars, make it not blindly copy what
AFComputedVariable does.
Extra: kill a temporary variable.
These changes are partly taken from
I96785c6c5fdf381c21d5f8930ee12e706abb7f3f.

Some of these are transformed into real unit tests, while the
AbuseFilterSaveTest class is refactored to avoid using the DB and to use
a lot more of mocks and DI.
