r5104: - added support for task based servers. These are servers that within themselves are run as a single process, but run as a child of the main process when smbd is run in the standard model, and run as part of the main process when in the single mode. - rewrote the winbind template code to use the new task services. Also fixed the packet queueing - got rid of event_context_merge() as it is no longer needed (This used to be commit 339964a596689278d2138cff05d7d444798a3504)

r7294: implemented the irpc messaging system. This is the core of the management system I proposed on samba-technical a couple of days ago. Essentially it is a very lightweight way for any code in Samba to make IDL based rpc calls to anywhere else in the code, without the client or server having to go to the trouble of setting up a full rpc service. It can be used with any of our existing IDL, but I expect it will mostly be used for a new set of Samba specific management calls. The LOCAL-IRPC torture test demonstrates how it can be used by calling the echo_AddOne() call over this transport. (This used to be commit 3d589a09954eb8b318f567e1150b0c27412fb942)
