Fix 10-20 PHP issues in MediaWiki core found by static code analysis (I)

MediaWiki continuous integration now runs Phan. Phan is a static code analyser for PHP. Phan highlighted a lot of issues. Until those issues are fixed in the MediaWiki core code repository, these issues have been temporarily suppressed (so they will not be shown) in the suppress_issue_types array in Phan's config.php file.

Technical requirements:

You are expected to

  • have some basic understanding of PHP
  • install Phan locally
  • manually remove some issue types from the suppress_issue_types array
  • run Phan locally
  • check Phan's output
  • fix 10-20 of the errors in the output
  • submit your patch in Wikimedia Gerrit. Make sure the commit message has the line "Bug: T153252"

If you run into any problems with Phan, please ask on Phan's Discussion page on the wiki (as there will be more people seeing it than in this GCI task.)
