Error while rewriting a BUILT-IN function with args passed by reference

[mpyw]

This issue is related to #33 #39, but it's still reproducible on built-in functions. If we add the following test, it will be failed.

    public function testReimplementFuncWithPassedByReference()
    {
        $array = [3, 6, 4, 8, 1, 0];
        test::func('demo', 'sort', function (array &$array) {
            usort($array, function ($x) { return $x - $y; });
        });
        sort($array);
        verify($array)->equals([0, 1, 3, 4, 6, 8]);
    }

Encountered this problem when trying to mock socket_recv which write results to a reference parameters.

the same issue is happening here when using __call and referenced parameters
In php it is not possible to pass arguments as variadic or using __call and have them be "by reference"
So basically all arguments passed to
__call($name, $arguments)
__callStatic(...)
myfunc(...$args)
are none reference ones and it is not possible to call a function below and return the modified value back
The code in InstanceProxy and the one for mocking built in functions both have this issue.
InstanceProxy does not produce an error, but you won´t get back any result.
The only way to "fix" that is to create a new function with the same parameter definition as before not using any func_get_args().
Even worse, if you mock the function preg_match, further calls will result in an error, even if test::clean has been called.
