r2573: - added a configure test for nanosecond time resolution in struct stat

  (recently Linux systems support this, allowing us to support the
  full resolution in NTTIME)

- use nanosecond resolution in the posix backend if available

- moved the configure tests and list of object files for the posix
  backend into ntvfs/posix/ to keep them more neatlly separated.
(This used to be commit d92ad9f307fe16a3b253a0555b437f14c94b4dd7)
