fde4363f58 smbd: Add filename_convert_dirfsp()
As part of the filename_convert() process, keep a pathref dirfsp of
the containing directory for later use. This avoids having to do
another non_widelink_open() on every SMB2_CREATE and ntcreate&x in
later patches.

Future work will be to go through other filename_convert() calls and
make them use filename_convert_dirfsp(). If we manage to convert all
of them except the one in filename_convert_dirfsp() itself, we can
simplify filename_convert() and unix_convert() significantly.

Too large a patch, but I don't know how to split this up into smaller
logic pieces.

c4d4fa68d6 smbd: Add get_real_filename_at()
Make get_real_filename() a wrapper.

Right now shadow_copy2 does a fallback to do get_real_filename() on
the twrp=0 tree in case of snapdirseverywhere because snapdirs can be
somewhere deep in the tree, and doing that correctly would be a
full-tree walk. I'd say that snapdirseverywhere is impossible to
implement if you want symlink safety, i.e. careful top-down tree
traversal together with snapdirseverywhere. If you have
snapdirseverywhere you need to pass down the full path very deep down,
which contradicts our fd-based approach we want to take.

Also, I believe that our test does not 100% correctly reflect what
actually is there: My understanding is that if you activate
snapdirseverywhere for example in GPFS, you see all snapshots at every
level (this would need to be verified). Our test does something more
nasty: It creates and tests a specific snapshot only at one place deep
in the directory hierarchy, which makes it impossible to find without
the full path.

This is all a big mess, but for now we need to deal with it. This adds
the twrp=0 fallback to core smbd, but I don't see any other way to do
that properly. And I do want a fd-based getrealfilename....

02f6130c90 vfs: Add SMB_VFS_GET_REAL_FILENAME_AT
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.

804a19ca5d smbd: Pass up stat-info from openat_pathref_fsp() on error
If openat_pathref_fsp() fails, callers might want to inspect the stat
info. If we really failed on STOPPED_ON_SYMLINK, the caller might need
to know this, although openat_pathref_fsp() masked this error.

As there is no smb_fname->fsp returned from openat_pathref_fsp() on
error, we need to pass this up in smb_fname itself.

This essentially reverts de439cd03047, which does basically the same
thing but is too specific. We need to cover the general !O_PATH case
more broadly.
