[PATCH 00/15] remote-mediawiki: various fixes to make tests pass

I had occasion to look at remote-mediawiki and I couldn't even get the test suite to run. The patches below have more detail but there's issues like a hard error on any Perl release newer than ones released in 2013, and the MediaWiki release it tries to use spewing errors on any modern PHP version.

This series fixes these issues. With it applied it's possible to run the tests, and they all pass.
