* Update CallMap.php with information from docs.php.net
* Undo possibly inaccurate information from docs.php.net
* Fix bug in ReflectionMethod::invoke*() signature
http://php.net/manual/en/reflectionmethod.invoke.php had a misleading
method signature description section
This fixes the following false-positive:
```php
function a(): bool {
$a = function(): bool { return true; }
return $a->call(new stdClass);
}
```
where psalm previously complained about (wrongly) inferred type to be
Closure
Affected functions/methods:
* `iterator_apply()`
* `iterator_count()`
* `IteratorIterator::__construct()`
* `iterator_to_array()`
This fixes the following false-positive:
```php
class Iter extends IteratorIterator {
public function __construct(Traversable $a) {
parent::__construct($a);
}
}
```
where psalm previously wanted `parent::__construct()` argument to be
`traversable` (all-lowercase).
