If one is passed to filename_convert(), it will error out there

This one is subtle. If an SMB1 request has both a DFS path and a @GMT token,
the unix_convert() inside the DFS path processing will remove the @GMT
token, not allowing the subsequent unix_convert() inside filename_convert()
to see it. By returning it from dfs_redirect() we can ensure it's correctly
added to the smb_filename returned from filename_convert().

Note that parent_pathref() must succeed before we call SMB_VFS_READ_DFS_PATHAT().
If parent_pathref() fails, just step back a component without calling
SMB_VFS_READ_DFS_PATHAT().
There are no longer any non-relative uses of SMB_VFS_READ_DFS_PATHAT().

The only function that sets conn->connectpath is set_conn_connectpath() and

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
