Non web interfaces with WordPress (such as wp-cli) need to be able to bypass certain checks in the bootstrap process. This introduces three new filters to allow for those checks to be skipped.
1. Provides a way of forcefully bypassing wp_maintenance().
2. Provides a way of forcefully bypassing wp_debug_mode(). See https://github.com/wp-cli/wp-cli/issues/177
3. Provide a way of forcefully skipping loading wp-content/advance-cache.php. See https://github.com/wp-cli/wp-cli/pull/164
These filters should not be used by plugins (in fact, they run before plugins are loaded, so they can't be used by plugins). In general, they should only be used in non-web interactions with WordPress.
See <a href="https://core.trac.wordpress.org/ticket/34936">#34936</a>.
