The modules that change the pathname need a synthetic_pathref now for
the SMB_VFS_NEXT_DISK_FREE() call. I think this is the right thing to
do anyway, as this goes through all the path scrutiny and does not
depend on direct multi-component paths anymore.

[MS-FSA] 2.1.5.15.12.1 Algorithm for Performing Stream Rename
is simpler and diffent enough from renaming a file or directory that I
believe a separate VFS operation is justified instead of tunneling it
through the renameat call. For example it's only possible to rename
streams within a file, so only one stream open fsp and a newname which
is guaranteed to be a stream name is necessary.
Add stub implementations to our streams modules, to be filled later.

So far we only call CONNECTPATH on full paths. In the future, we'll
have a call that will not have converted a relative path to absolute
just for efficiency reasons. To give shadow_copy2 the chance to still
find the snapshot directory, pass the dirfsp down to it.

This prepares the later introduction of VFS_OPEN_HOW_RESOLVE_NO_SYMLINKS,
which will be used to make use of RESOLVE_NO_SYMLINKS on linux with openat2().
Right now all terminal VFS objects reject any resolve bits with ENOSYS.
So we only prepare the vfs layer for now without any real change.
But this will make backports to 4.17 much easier.

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.

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.

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.
