da3053048c Merge of new 2.2 code into HEAD (Gerald I hate you :-) :-). Allows new SAMR 
RPC code to merge with new passdb code.
Currently rpcclient doesn't compile. I'm working on it...

b43b2e4f8a Restructuring of the code to remove dos_ChDir/dos_GetWd and re-vector them 
through the VFS. All file access/directory access code in smbd should now
go via the vfs. Added vfs_chown/vfs_chmod calls. Still looking at vfs_get_nt_acl()
vfs_set_nt_acl() call API design.

7a3795d5df Fix to allow a timestamp of zero to cause an instantaneous changenotify 
scan - then call this from renames. This allows instantaneous update for
W2k renames.

b2d01bd2db totally rewrote the async signal, notification and oplock notification 
handling in Samba. This was needed due to several limitations and
races in the previous code - as a side effect the new code is much
cleaner :)

in summary:

- changed sys_select() to avoid a signal/select race condition. It is a
  rare race but once we have signals doing notification and oplocks it
  is important.

- changed our main processing loop to take advantage of the new
  sys_select semantics

- split the notify code into implementaion dependent and general
  parts. Added the following structure that defines an implementation:

struct cnotify_fns {
	void * (*register_notify)(connection_struct *conn, char *path, uint32 flags);
	BOOL (*check_notify)(connection_struct *conn, uint16 vuid, char *path, uint32 flags, void *data, time_t t);
	void (*remove_notify)(void *data);
};


then I wrote two implementations, one using hash/poll (like our old
code) and the other using the new Linux kernel change notify. It
should be easy to add other change notify implementations by creating
a sructure of the above type.

- fixed a bug in change notify where we were returning the wrong error
  code.

- rewrote the core change notify code to be much simpler

- moved to real-time signals for leases and change notify

Amazingly, it all seems to work. I was very surprised!
