History
Andrew Tridgell cb0cd473a0 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 d92ad9f307)

This is the base of the new NTVFS subsystem for Samba. The model for
NTVFS backends is quite different than for the older style VFS
backends, in particular:

- the NTVFS backends receive windows style file names, although they
  are in the unix charset (usually UTF8). This means the backend is
  responsible for mapping windows filename conventions to unix
  filename conventions if necessary

- the NTVFS backends are responsible for changing effective UID before
  calling any OS local filesystem operations (if needed). The
  become_*() functions are provided to make this easier.

- the NTVFS backends are responsible for resolving DFS paths

- each NTVFS backend handles either disk, printer or IPC$ shares,
  rather than one backend handling all types

- the entry points of the NTVFS backends correspond closely with basic
  SMB operations, wheres the old VFS was modelled directly on the
  POSIX filesystem interface.

- the NTVFS backends are responsible for all semantic mappings, such
  as mapping dos file attributes, ACLs, file ownership and file times
