Make it clear that being an alternate data stream handle is much more
a fsp property than a file name property.

To me this is more descriptive than "fsp->base_fsp != NULL". If this
turns out to be a performance problem, I would go and make this a
static inline in smbd/proto.h.

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.

Remove my poor imitation of synthetic_pathref(), just call the real thing.
We need to go through the full VFS stack here to get
the ino correct to get the fsp handle.

Use new smb_fname->fsp->base_fsp parameter in get_xattr_size(), change name parameter to NULL.
If openat_pathref_fsp() fails, return the correct error code (thanks Ralph!).

There can never be EA's on a symlink. Windows will never
see a symlink, and in SMB_FILENAME_POSIX_PATH mode we don't
allow EA's on a symlink.
All of the previous code boiled down to errno = ENOENT, return -1
so make that explicit.

Add support for streams that are larger than 64 KiB in size. Upper
and lower bound are controlled by the parameters smbd max_xattr_size.
Testing against ReFS on Windows (where ADS size is limited in size
shows the server responding with STATUS_FILESYSTEM_LIMITATION.
Do the same in samba for this case.
Currently, large xattrs are supported in FreeBSD.

When we used vfs_fake_fd() we should use vfs_fake_fd_close()
in order to have things symetric.
That may allows us to change vfs_fake_fd() internally if required.

This replaces the code in a bunch of places where we choose between stat() and
lstat() based on req->posix_pathname. The new code inside vfs_stat() is based on
checking the smb_fname flag SMB_FILENAME_POSIX_PATH.
req->posix_pathname is inherited from the global POSIX pathnames state and the
smb_fname flags is also inherited from that indirectly via the UCF flags.
Tl;dr: no change in behaviour. :)
