if a directory is empty, only the 'marker' object `/` exists.
since not all s3 implementations return just the prefix when listing objects by prefix,
when listing objects by the folder prefix, nothing will be returned if the directory is empty.
by not including the trailing slash in the prefix, the folder marked will always be returned if it exists

Since we try to do range requests this will fail hard.
However since empty files are not that interesting to read anyways we
just read from an emptry memory stream.

If a file or folder in a directory doesn't have read permissions they
will not be shown
Note that enabling this option incurs a performance penalty additional
requests need to be made to get all the acl.
Additionally the acl resolving logic is fairly primitive at the moment
and might not work correctly in all setups (it should error to showing
the entry)

Currently you need to use `opendir` and then call `getMetadata` for
every file, which adds overhead because most storage backends already
get the metadata when doing the `opendir`.
While storagebackends can (and do) use caching to relief this problem,
this adds cache invalidation dificulties and only a limited number of
items are generally cached (to prevent memory usage exploding when
scanning large storages)
With this new methods storage backends can use the child metadata they
got from listing the folder to return metadata without having to keep
seperate caches.

To continue this formatting madness, here's a tiny patch that adds
unified formatting for control structures like if and loops as well as
classes, their methods and anonymous functions. This basically forces
the constructs to start on the same line. This is not exactly what PSR2
wants, but I think we can have a few exceptions with "our" style. The
starting of braces on the same line is pracrically standard for our
code.
This also removes and empty lines from method/function bodies at the
beginning and end.
