These stubs describe how code that is not available at analysis time should be
used. No implementations are necessary, just define the classes and their
methods and use phpdoc to describe what arguments are allowed.
Add configuration for running etsy/phan against core Adds the necessary configuration and stubs for phan static analysis to run against mediawiki core. A variety of fixes have been applied to core recently such with this current configuration we are completely passing, except for one issue with a bug in Phan (https://github.com/etsy/phan/issues/286) In it's current configuration Phan will detect fatal errors trying to access non existant classes, undefined method calls, and other errors. The analysis can be expanded as we cleanup more of the codebase. This is in preparation for working on getting the CI to run phan as part of the review process. I have found phan to be usefull in CirrusSearch (although with stricter config) for catching bugs and I think it could help in core as well. We arn't too far from being able to disable `null_casts_as_any_type`, there are only a few classes that need adjusting. Lots more work needs to be done to reduce `minimum_severity` from 10 to 5 (normal) or 0 (low).
