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.

Can you change the DEBUG(10,....)
calls to DBG_DEBUG(...) please ?

I'm trying to change all new code submissions
to the new:

/*
 * Debug levels matching RFC 3164
 */
#define DBGLVL_ERR       0      /* error conditions */
#define DBGLVL_WARNING   1      /* warning conditions */
#define DBGLVL_NOTICE    3      /* normal, but significant, condition */
#define DBGLVL_INFO      5      /* informational message */
#define DBGLVL_DEBUG    10      /* debug-level message */

#define DBG_ERR(...)            DBG_PREFIX(DBGLVL_ERR,          (__VA_ARGS__))
#define DBG_WARNING(...)        DBG_PREFIX(DBGLVL_WARNING,      (__VA_ARGS__))
#define DBG_NOTICE(...)         DBG_PREFIX(DBGLVL_NOTICE,       (__VA_ARGS__))
#define DBG_INFO(...)           DBG_PREFIX(DBGLVL_INFO,         (__VA_ARGS__))
#define DBG_DEBUG(...)          DBG_PREFIX(DBGLVL_DEBUG,        (__VA_ARGS__))

macros, and eventually retire DEBUG(x,..).

Cheers,

	Jeremy.
