Add the ReadDirPlus function call, wrapping ceph_readdirplus_r. Add DirEntryPlus which is a DirEntry plus a getter for the statx field. Add a test similar to the ReadDir test and (since it is possible to induce an error with ceph_readdirplus_r) a test for the error handling path to improve code coverage.
