Why:
* Maintenance scripts in core have bolierplate code that is
added before and after the class to allow directly running
the maintenance script.
* Running the maintenance script directly has been deprecated
since 1.40, so this boilerplate code is only to support a now
deprecated method of running maintenance scripts.
* This code cannot also be marked as covered, due to PHPUnit
not recognising code coverage for files.
* Therefore, it is best to ignore this boilerplate code in code
coverage reports as it cannot be marked as covered and also
is for deprecated code.
What:
* Wrap the boilerplate code (requiring Maintenance.php and then
later defining the maintenance script class and running if the
maintenance script was called directly) with @codeCoverageIgnore
comments.
* Some files use a different boilerplate code, however, these
should also be marked as ignored for coverage for the same
reason that coverage is not properly reported for files.

Make phan stricter about null types by setting null_casts_as_any_type to
false (the default in mediawiki-phan-config)
Remaining false positive issues are suppressed.
The suppression and the setting change can only be done together

This is important in long-running script so we can pick it up where it
had to be stopped or crashed (db read-only for example).

- waitForReplication is critical in such scripts, it has caused a major
outage in commons before.
- The extra sleep is not important for scripts that take a couple of
hours to finish but it is important for ones that take more than a
day. Because replication lag to secondary datacenter and non-core dbs
(cloud, backup source, analytics) is not reflected in waitForReplication
and running a maint script for an extended period of time will cause
issues for those.
You can see similar work done on similar scripts such as deleteAutoPatrolLogs.php

Introduce a new schema migration stage in which rev_actor is used
directly and the revision_actor_temp table is no longer needed. This
becomes the new "new" stage whereas the previous situation is now
termed SCHEMA_COMPAT_TEMP.
Introduce migrateRevisionActorTemp which copies data from
revision_actor_temp to rev_actor. The code is similar to
migrateImageCommentTemp.php except that it doesn't delete from the old
table.
Partial revert of c29909e59f. That change removed direct
references to $wgActorTableSchemaMigrationStage and made queries
involving revision_actor_temp be unconditional. Such changes need to be
reverted to make the use of revision_actor_temp be conditional again.
In ActorMigrationTest, I compacted provideGetJoin() and
provideGetWhere(), removing most of the duplication between expected
values. I gave all the stages a short name, and mostly used the name in
providers.
