Bug description:Include fails with toplevel symlink to /

Description:
------------
Tarball: http://stephan-suerken.de/tmp/php53include.tar.gz

Hi,

with a certain directory setup (symlink pointing to /, see file tree in
php53include.tar.gz) plus script call syntax (see scripts "ok" and "fail"
scripts in tarball), including a file meekly fails.

I have not completely debugged it, but afaics "php_resolve_path" fails were
it should not; I suspect some of the "canonize path" functions wrongly give
an error here.

Thanks,

Stephan

Test script:
---------------
Steps to reproduce:

1. Download: http://stephan-suerken.de/tmp/php53include.tar.gz
[as root]
2. cd /
3. tar xfz php53include.tar.gz
4. /phptest/fail


Expected result:
----------------
# manwe(CHROOT:sid-ui): /phptest
# root? ./ok 
/phpinclude/inc123.php: OK, INCLUDED



Actual result:
--------------
# manwe(CHROOT:sid-ui): /phptest
# root? ./fail
PHP Warning:  require(/phplink/phpinclude/inc123.php): failed to open
stream: No such file or directory in /phptest/test.php on line 2
PHP Fatal error:  require(): Failed opening required
'/phplink/phpinclude/inc123.php'
(include_path='.:/usr/share/php:/usr/share/pear') in /phptest/test.php on
line 2
