s3: smbd. Generic fix for incorrect reporting of stream dos attributes on a directory

According to MS-FSA a stream name does not have
separate DOS attribute metadata, so we must return
the DOS attribute from the base filename. With one caveat,
a non-default stream name can never be a directory.

As this is common to all streams data stores, we handle
it here instead of inside all stream VFS modules.

Otherwise identical logic would have to be added to
all streams modules in their [f]get_dos_attribute_fn()
VFS calls.

s3: vfs: vfs_streams_xattr: Don't blindly re-use the base file mode bits.

When returning the stat struct for an xattr stream,
we originally base the st_ex_mode field on the value
from the base file containing the xattr. If the base
file is a directory, it will have S_IFDIR set in st_ex_mode,
but streams can never be directories, they must be reported
as regular files.

The original code OR'ed in S_IFREG, but neglected to
AND out S_IFDIR.

Note this is not a complete to fix bug 13380 as
it doesn't fix the generic case with all streams
modules. See later fix and regression test.

winbind: Keep "force_reauth" in invalidate_cm_connection

Right now I don't see a way to actually force a re-serverauth
from the client side as long as an entry in netlogon_creds_cli.tdb
exists. cm_connect_netlogon goes through invalidate_cm_connection, and
this wipes our wish to force a reauthenticatoin. Keep this intact until
we actually did reauthenticate.

lib:replace: Fix linking when libtirpc-devel overwrites system headers

Some systems (like SUSE currently) install the new tirpc headers by
overwritting the existing system location used by gcc. This patch will
detect if the headers in the system location belong to tirpc or not.

ctdb-tests: Don't use nc -d or -w options

nmap-ncat is used in some distributions to replace netcat.  It has a
different meaning for these options.

We can get the same effect as the current combination of -d and -w by
piping a sleep process to nc.  Subsequent use of $! works because it
gets the last process in pipeline.

Note that redirecting from /dev/null doesn't work with some versions
of nc.  They just exit when they get EOF.

s3:auth: make use of make_{server,session}_info_anonymous()

It's important to have them separated from make_{server,session}_info_guest(),
because there's a fundamental difference between anonymous (the client requested
no authentication) and guest (the server lies about the authentication failure).

When it's really an anonymous connection, we should reflect that in the
resulting session info.

This should fix a problem where Windows 10 tries to join
a Samba hosted NT4 domain and has SMB2/3 enabled.

We no longer return SMB_SETUP_GUEST or SMB2_SESSION_FLAG_IS_GUEST
for true anonymous connections.

The commit message from a few commit before shows the resulting
auth_session_info change.
