Don't depend on fsp->fsp_flags.is_directory: We can always take the
parent directory fname, chdir into it and openat(O_PATH|O_NOFOLLOW)
the relative file name. To properly handle the symlink case without
having O_PATH, upon failure we need the call to
fstatat(AT_SYMLINK_NOFOLLOW) as a replacement for the fstat-call that
we can do when we successfully opened the relative file name with
O_NOFOLLOW.

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.

If it's really ENOMEM, shadow_copy2_convert() did set this itself. It
might also return ENOENT for example. Found this while working on
other patches.

This will allow us to remove the SMB1 server specific code
when we disable SMB1, and still retain the ability to negotiate
up from SMB1 -> SMB2 for old clients.

Restricts negotiation to SMB2-only. This will make it easier
to remove the SMB1-only parts of the server later.
The only allowed pre-SMB2 requests are a NBSSrequest
(to set the client NetBIOS name) and a 'normal' NBSSmessage
containing an SMB1 negprot. This allows smbd_smb2_server_connection_read_handler()
to work with older clients that use an initial SMB1negprot to
bootstrap into SMB2.
Eventually all other parts of the SMB1 server will
be removed.
Not yet used.

mapped_state is a special hack for authenticate_ldap_simple_bind_send()
in order to avoid some additional work in authsam_check_password_internals()
This doesn't apply here. We should also handle wbinfo -a
authentication UPN names, e.g. administrator@DOMAIN,
even if the account belongs to the local sam.
With this change the behavior is consistent also locally on DCs and
also an RODC can handle these requests locally for cached accounts.

mapped_state is only evaluated in authsam_check_password_internals()
of auth_sam.c in source4, so setting it in the auth3 code
doesn't make any difference. I've proved that with
an SMB_ASSERT() and a full pipeline not triggering it.

This is not really relevant for now, as USER_INFO_INTERACTIVE_LOGON is
not evaluated in the source3/auth stack. But better add it to
be consistent.
