orangefs: implement statx
Fortunately OrangeFS has had a getattr request mask for a long time. The server basically has two difficulty levels for attributes. Fetching any attribute except size requires communicating with the metadata server for that handle. Since all the attributes are right there, it makes sense to return them all. Fetching the size requires communicating with every I/O server (that the file is distributed across). Therefore if asked for anything except size, get everything except size, and if asked for size, get everything.
