SET_STAT_INVALID only sets nlink, not the other fields
We might consider to change SET_STAT_INVALID to always do ZERO_STRUCT

Found by the IBM checker.
Jeremy, you changed this from 'dirname == 0' which does not make sense at all
in the old code to '!dirname == 0' which from my point of view makes even less
sense, because the precedence of ! is according to Harbison/Steele higher than
the precedence of ==. Please check that the code now actually does what it's
supposed to do.
Thanks!

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!

Found by a "set but never used" warning. Thanks to talloc_tos() this was not
really a bug, but this way the code becomes much clearer.

new stream code. (1) In smbd/filename, don't split the name at
':' if we know it's a posix path (this should be parameterized....).
(2). When calling posix_mkdir, we get the flag FILE_FLAG_POSIX_SEMANTICS
passed to open_directory(). I know for a posix client lp_posix_pathnames
should be true (which is checked for in is_ntfs_stream_name() but we
have an explicit flag here, so let's use it.

This is the core of the streams support. The main change is that in
files_struct there is now a base_fsp pointer that holds the main file open
while a stream is open. This is necessary to get the rather strange delete
semantics right: You can't delete the main file while a stream is open without
FILE_SHARE_DELETE, and while a stream is open a successful unlink of the main
file leads to DELETE_PENDING for all further access on the main file or any
stream.

Based on jpeach's work, modified the streaminfo prototype
Make use of it in trans2.c together with marshall_stream_info()

I did not test it, but it should not affect cifsfs, there are special posix
calls that also return the stat information unfiltered.

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.

Now homes and printers shares can be accessed through the
registry meachanism on demand in pure registry configurations
with "config backend = registry" without the need to
have a special handler for these two.

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.

bind to a socket if we've already bound to one (this
prevents :
bind failed on port 445 socket_addr = 0.0.0.0.
Error = Address already in use
