 * CGI Mode detection and workaround
 *
 * Some hosts only give access to the PHP CGI binary, even for running CLI scripts. While problematic, it mostly works.
 * This trait detects PHP-CGI and manipulates $_GET in such a way that we populate the $argv and $argc global variables
 * in the same way that PHP-CLI would set them. This allows the CLI input object to work. Moreover, we unset the PHP
 * execution time limit, if possible, to prevent accidental timeouts.
