Nobody used that anymore, most callers had passed in NULL anyway.

Nobody does anything with this anymore, we just call ReadDirName() in
sequence or do a RewindDir(). So we don't have to look at offsets as
given by the file system anymore.

The Linux prototype for openat2 looks like this:
long openat2(int dirfd, const char *pathname,
struct open_how *how, size_t size);
where "struct open_how" is defined in "linux/openat2.h". It is
designed to be extensible with further flags.
The "size" parameter is required because there is no type checking
between userland and kernelspace, so the way for Linux to find which
version of open_how is being passed in is looking at the size:
"open_how" is expected to only every grow with additional fields,
should a change be necessary in the future.
Samba does not have this problem, we can typecheck the struct and
pointers, we expect all VFS modules to be compiled against the current
vfs.h.
For now this adds no functionality, but it will make further patches
much smaller.

Copy the logic from ceph_snap_gmt_get_real_filename(). This is
untested in autobuild, but as ceph is broken anyway due to
812cb602e3, we need to talk to the ceph developers before 4.17.

In a patchset that I'm working on right now there's the need to call
getrealfilename while the code does have a pathref fsp already
around. Doing the name-based call including non_widelink_open is not
necessary in this case. Start by adding the _at based call to the VFS.
For now, fall back to the name-based call. glusterfs-fuse will in a
future patch be converted to fgetxattr.

This makes it possible to more easily handle STOPPED_ON_SYMLINK vs
OBJECT_PATH_NOT_FOUND vs OBJECT_NAME_NOT_FOUND and so on. The next
patch needs this to properly handle symlinks.

Handle-based copy of ceph_snap_get_btime(). Uses
SMB_VFS_NEXT_FGETXATTR() instead of SMB_VFS_NEXT_GETXATTR().
Commented out as nothing uses it yet. This will change shortly.

The function returns ints and the callers expect ints. Declaring bool while
returning ints works, as generally compilers implement bools as ints.

@GMT tokens are still validated and stripped, but the previous version timestamp
is taken from the struct smb_filename twrp member.

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
