d088caa400 smbd: NULL out "fsp" in close_file()
Quite a few places already had this in the caller, but not all. Rename
close_file() to close_file_free() appropriately. We'll factor out
close_file_smb() doing only parts of close_file_free() later.

ff48422e63 s3: smbd: Fix SMB_VFS_FGET_NT_ACL/SMB_VFS_FSET_NT_ACL on stream handles.
As this is done on existing files, we know that
fsp->base_fsp != NULL and fsp->base_fsp->fh->fd != -1
(i.e. it's a pathref fd) for stream handles.

When getting and setting ACLs on stream handles,
use the fsp->base_fsp instead (as Windows does).

This not only fixes streams_xattr, but will
allow us to later analyze and remove all
special casing code for get/set ACLs on streams
handles.

Remove the knownfail.d/stream-acl file.

Not yet used. Passing as NULL means explicitly no wildcards

Could have used a bool here as in unlink_internals() but
using a string here makes the parameters more symmetrical

322574834f vfs: remove dirfsp arg from SMB_VFS_CREATE_FILE()
This was supposed to be a shortcut to avoid passing dirfsp around as an explicit
function argument throughout the whole codebase when the new VFS design idea was
based on using *AT functions throughout the VFS.

Now that we've opted for basing the VFS on handles and *AT functions will only
be used in a much more limitted extent, it makes sense to remove this internal
dirfsp reference, otherwise the combination of internal fsp->dirfsp and
smb_fname->fsp is going to be a tough to wrap your head around.

54883d4b3a smbd: move processing of root_dir_fid outside of SMB_VFS_CREATE_FILE()
The only two callers that pass a root_dir_fid != 0 are reply_ntcreate_and_X()
and call_nt_transact_create(). By moving root_dir_fid processing outside of
SMB_VFS_CREATE_FILE() we can avoid rewriting get_relative_fid_filename() to work
with *AT semantics and dirfsps.

Bonus points: the previous code in both functions passed fname to
filename_convert() which can't really have worked as it is relative to
root_dir_fid so filename_convert() will not be able to stat() the relative path
and it's components.

The only test I can find that uses a root dir_fid is raw.samba3rootdirfid and
that uses a handle on the share root which will work.
