PHP 8 Compatibility: import

[Gold]

This is to track patchsets that will bring the codebase up to be compliant with PHP 8.1.

The initial run through will be on a top level directory basis. i.e. the directories below htdocs. It will focus on the results from the PHPStan and Phan static analysis tools.

This bug tracks files in the import directory.

Testing will require identifying, from the patchset, where the code is used and then verifying that that area of the site still works in both PHP 7.4 and PHP 8.1.
