Add support for PHPStan, a static analyzer for PHP.
Because PHPStan requires PHP 7.1 or more recent, we cannot add it as a dev dependency in
composer.json. I worked around this by setting up a Makefile to download PHPStan separately as a self-contained PHAR archive.PHPStan offers different analysis levels, from 0 (loosest) to 7 (strictest). Right now I've set it at 1 and fixed most issues it reported. We can increase it and fix more issues in future PRs.
There are two issues I could not fix without some refactoring, so what I did was create a baseline file, which is basically the PHPStan equivalent of the
.rubucop_todo.ymlfile. Thephpstan-baselinemake target can be used to regenerate the file.
