Merge of sam sync code from TNG.
Reverse-engineered the sam replication protocol from staring at hex dumps for a while. It's pretty similar to the sam sync protocol with a couple of different delta header types. I wasn't able to figure out the format of the privilege stuff - needs more time and a whiteboard. (-: The impressive bit is that the sam sync stuff from tng basically just worked thanks mainly to Luke Leighton's efforts in this area. (This used to be commit 3a60cb44f22d5f3f8c78a56ed8f5ea4794cd7ab3)
