While checking a filter, if a variable is not set (e.g. added_lines for
an account creation), the VariableHolder will return a DNULL, rather
than a DUNDEFINED. This means that some filters will resume working, and
the WMF servers will stop getting AF warnings at a rate of 4 millions per
day. This also requires adjusting some tests to reflect the new
behaviour (which is actually the OLD behaviour, that filters had until
last year when we introduced the DUNDEFINED data type). It also requires
adjusting a check in the old parser, but that's not really relevant
because the plan is to remove the old parser before 1.36 is released
(see I0e75f334c7e0dfc1239f2e5f5f7d7452b0bbf29e).

These render string arguments with potentially sensitive information
that we don't want to store in debug logs. Use the standard
'exception' field instead per T233342, letting the central
logic be in charge of creating 'exception.trace' with the normalised
trace rendering and filtering logic we have there.

Using var_export for better visual effect, especially for arrays.
The result from /tools is much clearer and the 'wrong syntax' message is
a bit more explicative than before.

This was used to dynamically generate *_restriction_* variables.
However, it had two big problems:
- We only have i18n for 'create', 'move', 'edit', and 'upload' (the
default value of the global); other restrictions would show missing
messages in various pages.
- We had to access the global state in various points.
This change also makes some code in AbuseFilterVariableHolder simpler,
and also allows us to make AbuseFilterTest a unit test.

For the new parser, xhgui shows that AbuseFilterParser::getVarValue is
taking up a lot of time; in turn, most of the time spent inside
getVarValue is used to log the use of deprecated variables. Hence, given
that:
- We should keep the new parser performant
- There are tons of deprecated variables out there and they likely
won't be replaced
- Having gazillions of debugLog entries doesn't help
log them only in the cached phase.

I just realized that the parser is already throwing if it finds a
disabled variable. Hence, all calls to getVar with a disabled var are
from old entries and the like, and we don't care.

This also includes the filter ID. If the filter ID is not available, it
means that the user is using stuff like /tools, and they'll immediately
see the error.

This will help mitigating problems like T230256 by enforcing that the
requested variables must exist. For now, it will only log bad usages,
thus providing a way to identify affected filters and fix them.

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.

This is the proper solution to replace
Ia8e38ba25d1989fe71714d2b76891c4587921466, using a class member and an
additional method. Plus, change checkFilter not to accept a prefix, but a boolean indicating if the filter is global (as that's how it's used currently).
This change also fixes an issue which caused profiling data for local
filters to be mixed with profiling data for global filters with the same
ID.

This should allow more flexibility when checking syntax, and a saner
behaviour overall.
Aside from not throwing exception in certain cases, the results should
be almost equal to the ones you would get without this patch. However,
there are still a few things to improve (which for convenience I wrote
inside the parser test) and many to test.

These are specific tests for storeVarDump and loadVarDump, both alone
and in the context of running filters.
Also, include disabled variables in the VariableHolder object if they're
saved in the DB.

Try to get the groups from the var first, and compute them if they don't
exist. Use getEffectiveGroups instead of getGroups as it's done when
setting the lazy var loader. Avoid a pointless array_intersect within an
array_diff. Remove Phan @suppress and add docblock to make it pass.

It's totally pointless to recreate all variable names, since we already
have them in builderValues. The only exception is for _restrictions
variables, although they should be handled in builderValues too.

The variable was disabled with I7f13773766e12f3d4b86451fdf3ae23e067ac373
in 2016, but not in the same way as old_text and old_html were disabled
in 2009. This patch uses the methods introduced with
Ife168522e6b1d8eb94ebbb8a16ae8831ec1dc497 to disable minor_edit in a
standard way, so that it won't be showed in new AbuseLog entries, and
won't be usable when writing filter syntax.
A warning will be emitted if a pre-existing filter is using it, so that
we'll be able to completely disable it in the future.

For the moment, this is a simple workaround to get them back working.
Ideally we'd also need a maintenance script to update var dumps as I
wrote in the task, but it needs more thinking (see Phab).

Variables regarding title (full list in task description) are quite
deceiving, since they use "text" instead of "title". As proposed in the
task, this is the first patch to add aliases for those variables and
slightly deprecate the old ones. In the future we may be able to replace
every occurrence (either with a search function or directly on the
database), but even a coexistence would be enough to avoid
confusion. A wfDebug log is generated whenever a deprecated variable is
parsed. The "article_" prefix is also changed to "title_", in the same
way as above.
Also, added a hook which other extension may use to specify their
deprecated variables, which will be handled the same as core ones.
