Description:
------------
because filternames can contain slashes (convert.iconv.from-enc/to-enc) it should be possible to pass URL-encodet filternames to php://filter

Reproduce code:
---------------
<?php
$str = 'php://filter/read=convert.iconv.ISO-8859-15%2FUTF-8/resource=data://text/plain,foobar';
                                             ^ url encoded slash

Expected result:
----------------
string(6) "foobar"


Actual result:
--------------
Warning:  file_get_contents(): unable to create or locate filter "convert.iconv.ISO-8859-15%2FUTF-8" in /var/www/foo/a.php on line 34
Warning:  file_get_contents(): Unable to create filter (convert.iconv.ISO-8859-15%2FUTF-8) in /var/www/foo/a.php on line 34

If the filtername is not URL encoded than i get this:
Warning: readfile(): unable to create or locate filter "convert.iconv.ISO-8859-15" in ...
Warning: readfile(): Unable to create filter (convert.iconv.ISO-8859-15) in ...
Warning: readfile(): unable to locate filter "UTF-8" in ...
Warning: readfile(): Unable to create filter (UTF-8) in ...

And this should work because..? (IMO, it's expected, you pass invalid data -> you get an error..simple.)

This should work because otherwise there is no way to pass valid and existing filternames as URIs to PHP.
(This bug is approved by hartmut btw.)

A possible fix would be to urldecode() filter names in the php:// wrapper before passing them to the filter API:

The patch works perfectly for me.
