Previously, AbuseFilterHooks would proxy the data from a slower backend
(db-replicated) to a faster one (hash) reusing the same key. This change
makes it use a dedicated key, so that the "main" key can be kept
internal inside the upcoming BlockAutopromoteStore.

- Add a helper method to output an unrecoverable error, comprising a
button to go back to the filters list;
- Move the token check to attemptSave, so to make the conditionals
easier to read, and group errors together
- Make buildFilterEditor take an HTML parameter for the error, so the
caller can specify whether it's error or warning
- Move the check for non-existing filters out of buildFilterEditor
- Add a bunch of typehints
- Don't set af_throttled and af_hit_count in the empty row template, but
set af_deleted (these are only used in buildFilterEditor)
- Make AbuseFilter::translateFromHistory consistently include the af_global
property (previously it would only be set for global filters; this error
was introduced when first implementing global filters)
- The only user-facing change is that, when trying to use a custom
warning/disallow message on a global filter, this is now considered a
non-fatal error, so we now show the editing interface (and not just an
unrecoverable error).
The next step is resolving the @todo in buildFilterEditor about null
checks.

This commit avoids direct queries on the DB, which is already an
improvement. It also adds some TODO comments for future improvements,
mostly things that depend on core changes.

There's no point in repeating the action name, because it's already used
as key. We can then flatten the array and just keep the parameters in
the third nesting level.

The schema changes hook was chosen because the handler is very long. The
test ones were chosen to keep test things away from actual code.

So that sysadmins can further customize the extension. It was also wrong
to use the same variable for many different things.
Note that there's no associated patch in wmf-config because we use the
defaults. However, before merging this patch, please recheck that
AbuseFilterRestrictions and AbuseFilterDisallowGlobalLocalBlocks aren't
used there (https://codesearch.wmflabs.org/operations/?q=AbuseFilterDisallowGlobalLocalBlocks%7CAbuseFilterRestrictions&i=nope&files=&repos=)

This hook is called on every request, even for view actions, hence it's
a hot spot and a potential source of performance issues. We can slightly
optimize it by avoiding a cache lookup if blockautopromote is disabled.
Note: this won't really have an impact on WMF wikis since blockautopromote
is enabled almost everywhere.

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.

This patch addresses two issues observed in WMF production:
- Specifying a search mode without a search pattern would result in a
call to mb_stripos (in AbuseFilterPager) with an empty delimiter,
which triggers a PHP warning. Avoid this by checking that the search
pattern is not the empty string, and unset the search mode if that's
the case.
- Trying to use an invalid search mode would result in an unhandled
LogicException. We have some code in place to check the validity of
the URL parameter, but the relevant code didn't reset the search mode
to null, hence AbuseFilterPager would throw before we can show a
pretty error to the user.

It doesn't make much sense to try to remove implicit groups like 'user'
and '*'. As a matter of fact, these groups are also excluded in
AbuseFilterViewRevert when undoing degroups.

This method was divided into multiple, shorter methods. We now have a
dedicated method for imports, and one for everything else, plus a method
for loading actions. Merged a conditional for when the token didn't
match. Avoid returning Status objects with data inside as it's too
difficult to properly infer types for those.
This is still not perfect, and another round of simplification might be
necessary before this class can be updated to use the upcoming Filter
value objects.

While this might seem a small change, it removes the last remaining
coupling between SpecialAbuseFilter and the *View classes, that were
forming a huge tangle.

Don't create <a> tags without a href. Show a placeholder
message instead of nothing (alternatively, we could create
a new message for each existing one).

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).

This code was simply caching the AbuseFilter::$tagsToSet property, but
this is not necessary. The only tag that can be buffered during edit
stashing is the conds limit tag. So we just save whether the conds limit
was hit, and apply the tag from a single point afterwards.
Also avoid checking whether 'tag' is enabled as an action, since this tag
should always be added when applicable.
Next step is creating some sort of Watcher service that will do
everything on its own: check whether the limit was hit, save this
information, and tag the action later.

- Depend on a generic IContextSource rather than SpecialAbuseFilter
(lower coupling);
- Inject a LinkRenderer (IContextSource doesn't have a ::getLinkRenderer
method)
- Add a helper method in SpecialAbuseFilter to get the page title, that
can also be used elsewhere (and the name constant can be made private
now)
- Pull down the mFilter property (and rename it to just 'filter') to
classes that actually need it. Some classes didn't need this at all
and the types were different among subclasses
Now the only cause of coupling between the View classes and
SpecialAbuseFilter is the static call in getTitle.
