Stefan Metzmacher 9ef33f5f5c r15734: This is a major change to the NTVFS subsystem: 
- to use a struct ntvfs_handle instead of a uint16_t fnum.
  (to make it independend from the frontend protocol)
- the allocation of handles now is provided by the frontend
  (smbsrv_*) via callbacks and not by each backend module
- this also makes sure that file handles are only passed
  to the ntvfs subsystem when the tcon and session matches,
  so modules can rely on this and need to check this.
- this allows multiple modules in the ntvfs module chain
  to allocate file handles. This can be used for virtual
  files like "\\$Extend\\$Quota:$Q:$INDEX_ALLOCATION"...
- also this will make SMB2 with 128 bit file handles possible

README 

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
