This method actually consists of two: add derived vars, and initialize
content vars. The former part depends on no parameters of this method.
On the other hand, the latter part combines multiple implementations
for some of the content variables using branching.
The branching is a dirty workaround and inferior to the GRASP principle:
"When related alternatives or behaviors vary by type, assign
responsibility for the behavior to the types for which the behavior
varies."
In other words, the callers (extensions) should be responsible for
choosing the initialization strategy themselves, instead of letting
VariableGenerator figure it out.
As the first step, split the former part to a separate method.
For now, it will be implicitly called by ::addEditVars.

Protected effectively means "public to subclasses" and should be
avoided for the same reasons as marking everything as public should
be avoided.

Abuse filter needs to check both if the update is available and if the
page is rendered. This is the exact issue FlaggedRevs have:

When forFilter is true and PreparedUpdate is available
(most save operations), retrieve all_links from
PreparedUpdate::getParserOutputForMetaData. Otherwise
do what was done before.
Note that this change probably leaves some dead code. It will be dealt
with later.
NOTE: this changes code potentially executed on every save operation.

The method for old_links retrieval depends on the "forFilter"
value, which we know in advance. If it's true, old_links should
be retrieved from the database. Make a case in the switch
that does nothing but retrieves links from the database,
and direct the evaluation to it.
This change was split from I3628a56e5 to make its review easier.
NOTE: this changes code potentially executed on every save operation.

We might consider adding an in-process cache because there

Each generator knows in which situation it is executed, and it
can pass this information to the computer. VariableHolder should
just hold the variables.

These are apparently the only two variables for which we can
quickly determine their value in such simple way.
Later, we can also try it for recent contributions.

This was most definitely my intention when I introduced the concept of
"generic vars", so it's a bit surprising to discover, 3.5 years later,
that the timestamp isn't computed there.
Also make the timestamp always be a string for consistency, since that's
the type documented on mw.org. I've manually checked all filters on
Wikimedia wikis using the timestamp variable, and added explicit int
casts where needed (although I think they'd still work due to implicit
casts).

The check was not consistent and the code could still crash
when $oldContent was null. RevisionRecord:getContent only
returns null when audience check fails, but we don't ask
for that.

Previously, for non-newly-created pages, AbuseFilter would get the text
for filtering twice: once in AbuseFilterHooks::filterEdit(), and then
again in RunVariableGenerator::getEditTextForFiltering(). (Plus another
call for the text of the previous revision.) The first copy of the text
is only passed into RunVariableGenerator::getEditVars(), and there only
used if the title doesn’t exist, otherwise it’s overwritten with the
second copy. Instead, let’s make AbuseFilterHooks not get the text at
all, and only get the text from the content when we actually need it
(the content is new).

The hook names contain a dash, which is mapped to an underscore by the
hook runner (see Ie8c8fb603b33ff95c8f8d52f392227f147c528d8), and the
previous method names weren't matching this.

With explicit calls it's easier to see what method is being used,
whether it's deprecated, etc. Some methods here are in fact deprecated
or already have a proper replacement, but this is left for a follow-up.

Additionally, avoid building Title objects in LazyVariableComputer, it
just adds a dependency on TitleFactory and creating mocks is more
complicated, but it's pointless because the caller already has a Title
object.
And also stop using Title::getEarliestRevTime(), since the replacement
is easy (we already have a RevisionLookup).
Note for reviewers about renames:
- Code VariableGeneratorDBTest was moved to LazyVariableComputerDBTest,
RCVariableGeneratorTest, and AbuseFilterVariableGeneratorTest
- AbuseFilterVariableGenerator test was moved into a dedicated
directory, methods were changed not to test the var values

So we can use DI in all generators. Some improvements were deliberately
omitted, e.g. injecting more services and relaxing User/Title to
UserIdentity/LinkTarget, and they'll be included in a subsequent commit.

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 use, and it was a bit harder to remove because it was
buried inside AFComputedVariable. Starting with
I4444cada720ab62d187f2dd0c4760697e465f2ff, we can freely change the
parameters to AFComputedVariable without breaking old log entries.
Note, we still need a fallback for other extensions calling this
method...

Remove $title->exists() from the check, so we have the following
changes:
- The AbuseLog will add a diff link for page creations
- Searching the AbuseLog for impact:saved will include page creations
- We don't have to recreate the WikiPage again in RunVariableGenerator
Also remove an old reference to "bug 31656": that comment was added in
rEABFefecf8b2441ae2f31f924ff33103f5affe5d1d62, which changed
Article::getContent() to Article::getRevision()->getRawText(). Nowadays
we don't even use Article anymore, and that conditional isn't even for
retrieving the page content, so the comment is wrong.
Add logging for when the Title object cannot exist, as this should never
happen in the context of the EditFilterMergedContent hook, and always
create a WikiPage. Some signatures were changed to require a WikiPage
object now, and every caller updated to provide it.

Ideally, this might live in MediaWikiIntegrationTestCase. For the
createaccount one, AuthManager should also provide a method to log the
creation, because currently we are forced to copypaste that code here.
- Add the missing tests for 'upload' in RCVariableGenerator, and adjust
the existing ones (delete file afterwards, more tablesUsed, use the
right extension).
- Exclude from the coverage report a couple of lines which should
theoretically be unreachable. Escalate logging to WARN level, where it's
more likely to be spotted.
- Remove an unused method (RCVariableGenerator::newFromID). This denies
the need to maintain and cover it. We also don't want this generator
to act as a factory.
Overall, this change brings the coverage for RCVariableGenerator to 100%
