 * Initialisation code for all PHP processes.

 * This for PRODUCTION.
 *
 * PHP is configured to execute this file before the main script. This uses the
 * `auto_prepend_file` setting. This is currently enabled on web requests
 * only, not on Maintenance/CLI processes.
 *
 * This is executed in the same run-time as the main script, which means
 * it CAN expose state, such as variables and constants.
 *
 * However, as it runs literally before anything else, it cannot use
 * any MediaWiki state and no wmf-config or private configuration
 * variables.
