In order to avoid external dependencies on implementation details,
this change replaces CephFSError with the unexported cephFSError. In case
some application really needs access to the integer value, it can use
the pattern
var errno interface{ Errno() int }
if errors.As(err, errno) { ... errno.Errno() ... }

Add a Statx wrapper for ceph_statx.
Add a type wrapping the statx status info that exposes the various
fields from the C-struct.
Add a type wrapping struct timespec, based on golang's x/sys, for the
time fields in the struct.
Note that the ceph struct is not the same as the linux statx struct.

Now, the close function is idempotent wrt being called multiple times
on a valid file. Additionally, check the state of the file in various
functions to produce sensible errors, matching those cephfs itself
returns, if the object was not constructed properly.
