Not yet used, that comes when we add fruit_openat(). Passing cwdfsp as dirfsp
ensures when calling openat() we get the same behaviour as open().

There's a bunch of stuff that needs updating to work with atnames.

Not really used for now and marked with
SMB_ASSERT(dirfsp == conn->cwd_fsp)
because it needs to be updated later to work with real dirfsp.

As create_file_default() still need to be updated in the future to replace the

This denotes pure VFS layer dirfsps that are used in *AT varients of VFS
interface functions and which bypass the FSA layer, requiring special handling
in codepaths closing/freeing the fsp.

As fsp->fsp_name will be a AT-name in the future, we need something to retrieve
the full path for an fsp from for stuff like fsp_str_dbg().
As there are functions like vfs_stat_fsp() that have internal fallbacks to
path-based VFS functions if fsp->fh->fh == -1, having the original dirfsp as
part of the fsp helps in converting the internal VFS functions to AT versions.
In the future when all such internal fallbacks are eliminated we can remove
fsp->dirfsp to avoid the additional fd per fsp and use a fsp->path or similar.

The original idea of doing the fstat in create_internal_dirfsp() was to return
from the function with a valid file_id and that requires valid stat info.
However, as dirfsp->fh->fd will still be -1 at this point vfs_stat_fsp() will
fallback to path-based stat() which must be avoided.

opd->dname was only needed for debug messages, use opd->fsp_name for that. And
opd->fname can be just made a copy of smb_fname. This avoids calling

These are the functions that *create* dirfsps, they can't *take* dirfsps as that

Both functions just take a pathname and the internal opening of the underlying
fd is secured from symlink races by our chdir("p/a/t/h") ; open(".", O_RDONLY);

No change in behaviour. This just simplifies fd_open() a bit which will make it
easier to add an fd_openat() later.

Add a large comment inside process_symlink_open() explaining why we need to call
SMB_VFS_READLINKAT().
As we don't make use of the returned name and just rely on SMB_VFS_REALPATH()
doing its job, remove target_fname
