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.

Daimona Eaytoy 7bcb5ec2d5 Add a service to format filter specs
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 7c1d1c6d7d Return warnings from the parser, add warning for catch-all regexps
This commit introduces some boilerplate for emitting warnings from the
AbuseFilter parser, and also code for showing these warnings in the ace
editor. Adding new warnings should be as simple as appending to
AbuseFilterParser::warnings (and adding the relevant i18n).

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 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.

Daimona Eaytoy 416dcd9ba3 Simplify ViewEdit, round 2
- 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.

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 f0539e0c1e Represent new filters with null instead of 'new'
PHP is not strongly typed, so it's not a good idea to use scalars of
different types (here it's an integer vs the string 'new') to represent
different possibilities. This can have bad effects when type juggling
occurs, and it's also harder to figure out what the type of the
parameter can be (because a numeric ID might have been passed as a
string). Using integer vs null avoids all of this, and also allows us to
use nullable typehints.

These changes were partly copied from
If981cb35bf19a8469aa6c43c907e107cf8c65bc2 and should help with the
migration to the Filter value objects.

Daimona Eaytoy 1bdf4e5351 Rewrite the VariableHolder code to translate deprecated variables
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.
