Check or set whether WordPress is in “installation” mode.

If the `WP_INSTALLING` constant is defined during the bootstrap, `wp_installing()` will default to `true`.

function wp_installing( $is_installing = null ) {
	static $installing = null;

	// Support for the `WP_INSTALLING` constant, defined before WP is loaded.
	if ( is_null( $installing ) ) {
		$installing = defined( 'WP_INSTALLING' ) && WP_INSTALLING;
	}

	if ( ! is_null( $is_installing ) ) {
		$old_installing = $installing;
		$installing     = $is_installing;
		return (bool) $old_installing;
	}

	return (bool) $installing;
}
