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.

CephFS returns Linux-style struct dirent that has a d_type field.
It appears to properly make use of the field. This change exposes
the field using a DType type and associated constants as well
as a DType() function for the DirEntry.

The RewindDir is used by List and can be used independently. It
resets the open dir to the "start".
The List function and the accompanying DirEntries type allow one
to simply grab all the dir entries at once. The Names method on the
DirEntries type allows the user to get the most commonly wanted items
from the dir entries in one shot.

Add the Directory type and the OpenDir function to get an open
Directory and a Close function to close/free it.
