r4331: Implement SAMR query_dom_info-call info-level 8 server- and client-side,
based on samba4-idl. This saves us an enormous amount of totally unnecessary ldap-traffic when several hundreds of winbind-daemons query a Samba3 DC just to get the fake SAM-sequence-number (time(NULL)) by enumerating all users, all groups and all aliases when query-dom-info level 2 is used. Note that we apparently never get the sequence number right (we parse a uint32, although it's a uint64, at least in samba4 idl). For the time being, I would propose to stay with that behaviour. Guenther (This used to be commit f9ab15a986626581000d4b93961184c501f36b93)
