Description:
------------
The value of $name produced by __callStatic() is lower cased but the $name produced by the regular __call() is unchanged.

Please adjust __callStatic() so it doesn't change the case of $name.

Reproduce code:
---------------
class MethodTest {
    public static function __callStatic($name, $arguments) {
        echo "Calling static method '$name' "
             . implode(', ', $arguments). "\n";
    }
}

MethodTest::runTest('in static context');

Expected result:
----------------
Calling static method 'runTest' in static context


Actual result:
--------------
Calling static method 'runtest' in static context
