Mainly BDC-related changes.
* Added SEC_CHAN_BDC * Fix for endianness problem reported by Edan Idzerda <edan@mtu.edu>. A BUFFER2 is really a "unibuf" in my terminology and we should treat it as such. * Added some more common NT structures (BIGINT, BUFHDR2, BUFFER4). * Added NET_SAM_SYNC (-> NetDatabaseSync2) RPC for account replication. Still experimental and incomplete, with a few too many NULL security descriptors lying around (must go look at Jeremy's SD code). Haven't worked out password encryption yet either. However, the XXX_INFO structures I've added to rpc_netlogon.h are quite nice as they give some insight into how these objects are stored in the SAM.
