Description:
------------
The ReflectionParameter::getClass() method does not work properly if the reflected parameter uses "self" as type hint. Instead, a ReflectionException is thrown saying that the class "self" does not exist. Tested with 5.2 and 6.0.0-dev from Nov 22.

Reproduce code:
---------------
<?php
class stubParamTest
{
    function paramTest(self $param)
    {
        // nothing to do
    }
}
$test1 = new stubParamTest();
$test2 = new stubParamTest();
$test1->paramTest($test2);
$refParam = new ReflectionParameter(array('stubParamTest', 'paramTest'), 'param');
var_dump($refParam->getClass());
?>

Expected result:
----------------
object(ReflectionClass)[4]
  public 'name' => 'stubParamTest' (length=13)


Actual result:
--------------
Fatal error: Uncaught exception 'ReflectionException' with message 'Class self does not exist' in C:\apachefriends\xampp1.5.3a\xampp\htdocs\tests\type_hint_self.php:13 Stack trace: #0 C:\apachefriends\xampp1.5.3a\xampp\htdocs\tests\type_hint_self.php(13): ReflectionParameter->getClass() #1 {main} thrown in C:\apachefriends\xampp1.5.3a\xampp\htdocs\tests\type_hint_self.php on line 13

Same goes for "parent" which works as type hint but will make reflection try to look up a class called "parent" (and thus throw an exception)

http://sitten-polizei.de/bug39884.diff (CVS HEAD = PHP6, is probably easily backportable to 5.2)

Might need some work with Unicode, I haven't patched PHP in quite a while and have lost track of how Unicode semantics work in extensions...
