It turns out that this is a necessary operation, separate from statvfs. statvfs
can fail during tcon, so conn->fs_capabilities would never see that we support
streams on a particular share.
James, can you check that I got the darwin variant right? Thanks!

Based on jpeach's work, modified the streaminfo prototype
Make use of it in trans2.c together with marshall_stream_info()
(This used to be commit c34d729c7c)
As discussed with Volker, it is better to calculate FS capabilities at
connection time. We already do this with help of VFS statvfs() call
which allows to fill-in system-specific attributes including FS
capabilities. So just re-use it if you want to represent additional
capabilities in your modules. The only caution is that you need to
call underlying statvfs() call to actually get system-specific
capabilities (and other fields) added. Then add module-specific ones.

This makes sense as upper levels are only taking returned result of 0
(no error) into consideration when deciding whether to mark file
offline/online as returned from is_offline.
That means that we simply can move the decision down to VFS module and
clean up upper levels so that they always see only file status. If there
is an error when trying to identify file status, then VFS module could
decide what to return (offline or online) by itself -- after all, it
ought to have system-specific knowledge anyway.
(This used to be commit 75cc086614)
Offline files support and remote storage are for allowing communication with
backup and archiving tools that mark files moved to a tape library as offline.
We translate this info into corresponding CIFS offline file attribute and
mark an exported volume as remote storage.
Async I/O force is to allow selective redirection of I/O operations to asynchronous
processing in case it is viable at VFS module discretion. It is needed for
proper handling of offline files as performing regular I/O on offline file will
block smbd.

Up to now, get_nt_acl() took a files_struct pointer (fsp) and
a file name. All the underlying functions should need and now
do need (after the previous preparatory work), is a connection_struct
and a file name. The connection_struct is already there in the
vfs_handle passed to the vfs functions. So the files_struct
argument can be eliminated.
This eliminates the need of calling open_file_stat in a couple
of places to produce the fsp needed.

Replace smbd/posix_acls.c:get_nt_acl() by two funcions:
posix_get_nt_acl() and posix_fget_nt_acl(). The first
takes a connection struct and a file name instead of a
files_struct pointer. This is in preparation of changing
the vfs api for SMB_VFS_GET_NT_ACL.

bugs in various places whilst doing this (places that assumed
BOOL == int). I also need to fix the Samba4 pidl generation
(next checkin).

return to correctly return NT_STATUS_INVALID_OWNER if it
should be disallowed. Matches better what W2K3R3 does.
NFSv4 ACL module owners, please examine these changes.

changing the FindFirst response for the UNIX_INFO2 level to include
a length field before the name. The name is not required to be null
terminated. The length field does not count any null.
Also add call to chflags(2) in the default VFS module so that this
will work be default on BSD-derived platform. Add UNIX-INFO2 test
to the build farm to get some non-BSD coverage.
Jeremy and Jerry, please review for inclusion in 3.0.25.

for utimes - change the call to ntimes. This preserves
nsec timestamps we get from stat (if the system supports
it) and only maps back down to usec or sec resolution
on time set. Looks bigger than it is as I had to move
lots of internal code from using time_t and struct utimebuf
to struct timespec.

it should be abstracted a little higher up so other os'es can have an
entry, but it will take a bit more work. Thanks to Chetan Shringarpure
and Mathias Dietz.
I didn't increment the vfs number again because the kernel change notify
stuff hasn't been released yet anyway.

parameters
change notify = [yes]/no # do we do it at all
kernel change notify = [yes]/no # enable/disable inotify
Those who want FAM need to say
change notify = yes
vfs objects = notify_fam

modularizes our interface into the special posix API used on
the system. Without this patch the specific API flavor is
determined at compile time, something which severely limits
usability on systems with more than one file system. Our
first targets are AIX with its JFS and JFS2 APIs, at a later
stage also GPFS. But it's certainly not limited to IBM
stuff, this abstraction is also necessary for anything that
copes with NFSv4 ACLs. For this we will check in handling
very soon.
