Description:
------------
textdomain(null) throws a TypeError when strict_types is declared.

Doc:
https://secure.php.net/manual/en/function.textdomain.php#refsect1-function.textdomain-parameters

> Parameters
>  text_domain
>    The new message domain, or NULL to get the current setting without changing it

Without strict_types, it works fine(returns current setting).

Test script:
---------------
<?php
declare(strict_types=1);

var_dump(textdomain(null));


https://3v4l.org/BRUYj

https://3v4l.org/eCF0b

Expected result:
----------------
string(8) "messages"

Actual result:
--------------
PHP Fatal error:  Uncaught TypeError: textdomain() expects parameter 1 to be string, null given

Indeed, the arginfo[1] is insufficient.

This is not related to arginfo, the zpp signature does not allow it: https://github.com/php/php-src/blob/PHP-7.0.14/ext/gettext/gettext.c#L167

It should be "s?". Currently it handles the NULL case through a coercion to "".
