libcli/auth: Ensure that the dns_names in/out parameter is preserved

This is in dcerpc_netr_DsrUpdateReadOnlyServerDnsRecords, which has
status variables filled in by the server and placed in this in/out
array.

This showed up as a segfault in winbindd during RODC DNS update.

winbindd-irpc: Ensure not to call irpc_send_reply twice on error

As found during investigation of the previous commit, when the RPC
call fails totally, we must only try and send one error reply.

samba: Retain case sensitivity of cifs client

When a client supports extended security but server does not,
and that client, in Flags2 field of smb header indicates that

- it supports extended security negotiation
- it does not support security signatures
- it does not require security signatures

Samba server treats a client as a Vista client.

That turns off case sensitivity and that is a problem for cifs vfs client.

So include remote cifs client along with remote samba client
to not do so otherwise.
