nginx + FollowSymLinks owner verification

[Lekensteyn]

I consider it a feature if try_files and if can really check whether a file
exists or not (instead of accessible). I have cooked a patch [1] that
implements this functionality. Please review, comments are welcome.

Note: this patch changes behaviour. Previously, files which were not
accessible were simply skipped. After applying this patch, files which
exist, but are not accessible are not skipped. Maybe an option can be added
to try_files and if to toggle this behavior?

Regards,
Peter
