r22705: Implement new set_dc_type_and_flags() called based on the
information return from our DC in the DsEnumerateDomainTrusts() call. If the fails, we callback ot the older connect-to-the-remote-domain method. Note that this means we can only reliably expect the native_mode flag to be set for our own domain as this information in not available outside our primary domain from the trusted information. This is ok as we only really need the flag when trying to determine to enumerate domain local groups via RPC. Use the AD flag rather than the native_mode flag when using ldap to obtain the seq_num for a domain. (This used to be commit 4b4148a9642f03b8f27dda2132708bcc0cbb3b8e)
