This reverts commit 322574834f.
Not strictly a revert anymore, but for future work we do need "dirfsp"
in create_file_default() passed through the VFS.

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.

Useful if you want to stat/fstat/lstat relative to a directory without
doing chdir first.

We missed these values which follow from MS-FSCC 2.3.80 “FSCTL_OFFLOAD_READ
Reply”:
Flags (4 bytes):
A 32-bit unsigned integer that indicates which flags were returned for this
operation. Possible values for the flags follow. All unused bits are reserved
for future use, SHOULD be set to 0, and MUST be ignored.
OFFLOAD_READ_FLAG_ALL_ZERO_BEYOND_CURRENT_RANGE (0x00000001)
=> The data beyond the current range is logically equivalent to zero.
TransferLength (8 bytes):
A 64-bit unsigned integer that contains the amount, in bytes, of data that the
Token logically represents. This value indicates a contiguous region of the
file from the beginning of the requested offset in the FileOffset field in the
FSCTL_OFFLOAD_READ_INPUT data element (section 2.3.79). This value can be
smaller than the CopyLength field specified in the FSCTL_OFFLOAD_READ_INPUT
data element, which indicates that less data was logically
represented (logically read) with the Token than was requested. The value of
this field MUST be greater than 0x0000000000000000 and MUST be aligned to a
logical sector boundary on the volume.
As we currently only implement COPY_CHUNK over the OFFLOAD VFS interface, the
VFS COPY_CHUNK backend in vfs_default just sets both values to 0 and they are
unused in the SMB frontend.

With the removal of the call to flock LOCK_MAND, the only remaining use
of this VFS path is to register sharemodes with specific file systems.
Rename the VFS call to reflect that this is no longer related to flock.

Default is NTSTATUS version of parent_smb_fname(). Now
to replace all users of parent_smb_fname() with
SMB_VFS_PARENT_PATHNAME() and then remove parent_smb_fname().
Needed due to snapdirseverywhere code in vfs_shadow_copy2.

Now that handle based fdos_mode() is used everywhere we can be sure that we're
also always getting a handle in SMB_VFS_GET_COMPRESSION() so we can now safely
remove the path parameter. :)

This allows for optimisations in VFS module: by passing the dirfsp as an
additional arg, the function can check fsp->fsp_name->flags which may include eg
SMB_FILENAME_POSIX_PATH to trigger POSIX pathname processing.

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.

As create_file_default() still need to be updated in the future to replace the
SMB_VFS_STAT() calls with AT-based versions, it asserts (dirfsp ==
dirfsp->conn->cwd_fsp).

Currently identical to SMB_VFS_GET_NT_ACL().
Next, add to all VFS modules that implement
get_nt_acl and eventually remove get_nt_acl.
NB. Modules that use smb_vfs_assert_all_fns()
have SMB_VFS_GET_NT_ACL_AT() will not build
until they have this function added.
