[samba PATCH] vfs:ceph: convert to using ceph_statx structures and functions, when available

[Jeff Layton]

Add a configure test for the ceph_statx function, and use that to
determine whether to compile in new functions that use it and its
variants, or whether to use a the older code that fetches birthtimes
from an xattr.

For cephwrap_lstat, we can use ceph_statx with the AT_SYMLINK_NOFOLLOW
flag to get the right lookup semantics.

For setting the times via cephwrap_ntimes, We can just use ceph_setattrx
and pass them all in at the same time.
