Daimona Eaytoy fad9a11f7a Add a TextExtractor service
This is an important step towards removing the AbuseFilter class. Note:
proposals for the name of the new service are welcome.

Daimona Eaytoy b85f464530 Introduce a VariablesFormatter service
Moves more methods away from the AbuseFilter class. Testing
buildVarDumpTable is not easy because we'd have to parse the generated HTML.

Add namespaces, shorten class names.

Non-unit tests and AbuseFilterTest are untouched because those should be
refactored first.

Daimona Eaytoy c7f06750d6 Add a LazyVariableComputer service
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 requires a MessageLocalizer, which currently means providing the
main RequestContext. This is the only alternative right now, until core
provides a proper MessageLocalizer service (see T247127).

Daimona Eaytoy 5e609eb537 Add GlobalNameUtils class
This is just a temporary location for these two methods. Since they're
used a lot, having them in the AbuseFilter class means that the
dependency graph is unnecessarily complicated. Thus, since these methods
aren't doing much, they were moved to a dedicated class. Future todo is
finding an appropriate location, that might be either as part of another
service, or keep them in a Utilities class, perhaps a single class with
all util methods, rather than a specific class.

Daimona Eaytoy 904d9cddbb Represent Consequences with command objects
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.

Daimona Eaytoy 210cf29658 Add an interface for exporting/importing filters
The main benefit of having a dedicated interface is that we can easily
change the output format. So we're now using a custom array without
references to the DB schema, thus making the import/export process
completely independent from the schema.

Unfortunately, this isn't using DI completely, because of the

now.
Also, the types were weakened to UserIdentity, so the transition is

Daimona Eaytoy 9bc885b6b3 Add a ChangeTagger class
The logic about action IDs and the persistent buffer is now encapsulated
inside a single service, which is a step towards getting rid of global
state in the AbuseFilter class, and reducing the responsibilities of the
Runner.

An important change made here is that we now require a LinkTarget rather
than a Title. This removes a dependency on the Title class (a monster
object), makes tests simpler, and denies the need to inject a
TitleFactory. This means living without some bits of context (e.g. we're
no longer using makeTitleSafe to ensure a valid title, and we have to
build a "prefixedtext" manually), but this shouldn't be a problem, given
that the titles are only used to create a cache key: invalid titles are
not a problem, and concatenating namespace + title should always be
sufficient.

Daimona Eaytoy 1efc324d97 Use new services in AbuseFilterRunner
The first one is UserGroupManager, used for the 'degroup' action. This
is a simple one-line replacement (repeated twice), and the current code
was already using this service under the hood.

The second one is BlockUser, which is not a one-line change (but still
quite simple). In particular, this allows us to avoid duplication with
core logic when constructing the log entry (this is now done by
BlockUser).
