Description:
------------
When you using LimitIterator with offset that is larger or equal than inner 
iterator collection size and you invoke rewind() on LimitIterator then you get 
out of bounds exception.

You can solve that problem by handle exception from inner iterator's rewind() in 
LimitIterator::rewind()

Test script:
---------------
<?php
$some_array = array('foo', 'bar');
$iter = new ArrayIterator($some_array);
$limitIter = new LimitIterator($iter, 2);

foreach($limitIter as $value) {
    echo $value;
}

echo 'OK';
?>

Expected result:
----------------
only 'OK'

Actual result:
--------------
PHP Fatal error:  Uncaught exception 'OutOfBoundsException' with message 'Seek 
position 2 is out of range' in index.php:6

Stack trace:
#0 [internal function]: ArrayIterator->seek(2)
#1 index.php(6): LimitIterator->rewind()
#2 {main}
