Some features restrict access when filters are private. These features
should treat protected filters similarly.
If the user doesn't have view rights for protected filters:
- Disallow viewing of logs generated by protected filters
- Disallow querying of matches against protected filters
Bug: T363906

Some exposed variables (eg. `user_ip`) used in filters are sensitive
and need to only be available to restricted groups of users.
Back-end changes:
- Add `AbuseFilterProtectedVariables` which defines what variables are
protected by the new right `abusefilter-access-protected-vars`
- Add the concept of a `protected` variable, the use of which will
denote the entire filter as protected via a flag on `af_hidden`
New UX features:
- Display changes to the protected status of filters on history and diff
pages
- Check for protected variables and the right to see them in filter
validation and don't allow a filter to be saved if it uses a variable
that the user doesn't have access to
- Check for the right to view protected variables before allowing access
and edits to existing filters that use them

Protected variables will cause the filter using them to become
protected as well. `af_hidden` can be used to track this flag,
as it is a TINYINT and can be converted into a bitmask with no
schema changes.
This is not a backwards-compatible change, as now all checks must
check the `hidden` flag specifically or otherwise will be cast to
true if any flag is set.
To support this change:
- "hidden" is considered a flag set in the `af_hidden`. This is a
change in concept with no need for updates to the column values,
as there is currently only one flag in the bitmask.
- `Flag`s store the bitmask as well as the state of single flags
and can return either.
- Any checks against the `af_hidden` value no longer check a
boolean value and instead now check the `hidden` flag value.

After temporary accounts are enabled, filters that rely on an ip
in the `user_name` will fail (eg. `ip_in_range` and `ip_in_ranges`).
To keep these filters working:
- Expose the IP through another variable, `user_unnamed_ip`, that can be
used instead of `user_name`.
- The variable is scoped to only reveal the IPs of temporary accounts
and un-logged in users.
- Wikis that don't have temporary accounts enabled will be able to see
this variable but it won't provide information that `user_name`
wasn't already providing
- Introduce the concept of transforming variable values before writing
to the blob store and after retrieval, as IPs need to be deleted from
the logs eventually and can't be stored as-is in the amend-only blob
store

* Improve descriptions a bit, and move/merge any meaningful

are visually ignored and identical in each file, and often out of

This is a breaking change for the API: 'hidden' is now either true or
false, depending on afl_deleted. 'implicit' is no longer a possible
value, the caller should compute it instead if necessary.
Then simplify the remaining usage of isHidden, using a temporary private
method.

This replaces the previous pattern of callers having to use
RevisionLookup if the result was 'implicit'. Also, in some cases where
we were just hiding things if the visibility was !== true, properly
handle the implicit case by using the new method. Make the new method
return string constants rather than bool|string.
The new method also fixes some potential info leaks which happened when
the row was hidden, the user could view suppressed AbuseLog entries, but
the associated revision was also deleted and the user couldn't see it
(this shouldn't be relevant for WMF wikis since AF deletion is
oversight-level).
Also add a bunch of tests for the various cases to ensure we don't
regress again.

And report an invalid ID in this case. Also, assume that the filter is
hidden if the global DB is not available, for consistency with the UI.

So everything can be loaded using PSR-4. These classes weren't renamed,
nor the alias for the AbuseFilter class was deprecated, because they
should be refactored first.

This makes VariableHolder a true value object, and introduces a
stateless service, VariableManager, to operate on it.
Note, in theory, this new service is still cyclically coupled with
LazyVariableComputed. However, it's now two stateless service being
coupled, not two smart/god value objects, so we've still earned
something. For now, the dependency is hidden by using a callback. Some
alternatives for that are mentioned in a code comment.

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.
