We don't ever expect any filesystem IO operations to be called on an IPC shares,
so there's no need to initialize the module here.

The next commit adds the first call inside Samba to the VFS function
SMB_VFS_FGET_DOS_ATTRIBUTES() and therefor also to
vfs_gpfs_fget_dos_attributes(). No idea why gcc is generating this warning:

If we can access the path to a file, by default we have FILE_READ_ATTRIBUTES
from the containing directory. See the section: "Algorithm to Check Access to an
Existing File" in MS-FSA.pdf.
So it's also safe to use a root opened pathref fd, as the root open is done on
the final component after a chdir() to the parent directory was done while still
impersonating the use. Qed.

In all places where we access or modify a file or it's associated metadata, we
use fsp_get_io_fd() to fetch the low-level fd from the fsp. This ensures we
don't accidentally use a pathref fsp where the fd would be opened as root on
systems lacking O_PATH.

Most places take twrp from a local struct smb_filename variable that the
function is working on. Some don't for various reasons:
o synthetic_smb_fname_split() is only called in very few places where we don't
expect twrp paths
o implementations of SMB_VFS_GETWD(), SMB_VFS_FS_CAPABILITIES() and
SMB_VFS_REALPATH() return the systems view of cwd and realpath without twrp info
o VFS modules implementing previous-versions support (vfs_ceph_snapshots,
vfs_shadow_copy2, vfs_snapper) synthesize raw paths that are passed to VFS NEXT
functions and therefor do not use twrp
o vfs_fruit: macOS doesn't support VSS
o vfs_recycle: in recycle_create_dir() we need a raw OS path to create a directory
o vfs_virusfilter: a few places where we need raw OS paths
o vfs_xattr_tdb: needs a raw OS path for SMB_VFS_NEXT_STAT()
o printing and rpc server: don't support VSS
o vfs_default_durable_reconnect: no Durable Handles on VSS handles, this might
be enhances in the future. No idea if Windows supports this.
o get_real_filename_full_scan: hm.... FIXME??
o get_original_lcomp: working on a raw path
o msdfs: doesn't support VSS
o vfs_get_ntquota: synthesizes an smb_filename from ".", so doesn't support VSS
even though VFS modules implement it
o fd_open: conn_rootdir_fname is a raw path
o msg_file_was_renamed: obvious
o open_np_file: pipes don't support VSS
o Python bindings: get's a raw path from the caller
o set_conn_connectpath: raw path
o set_conn_connectpath: raw path
o torture: gets raw paths from the caller

The API call is already done as root user (become_root), so that the
lease contains the root user. The lease capability is already implied by
the root user, so the explicit call to linux_set_lease_capability is not
required.
