In;a=shortlog;h=refs/heads/session-info I have the changes I am currently proposing.  I've made them compile (including per-patch for most of them), and I hope I've split them up enough for adequate review.  I'll start testing them tomorrow, but for now I'm interested in any comments on what I've done and how I'm approaching the problem. 

I also need to write an upgrade function to upgrade the privilage.tdb,
which as far as I read the GIT history and code, has been host by order
dependent since 2005.  In fixing that, I'll move to a new DB format
using a 64 bit bitmask. 

The basic idea has been to adapt the source4 privilege code to use the
bitmap constants and LUID values from source3, and to adapt the source3
code to some of the structures used in IDL or source4.  

(This isn't a one-sided merge, other adaptations of the source4 code to
make this easier are already in the tree). 

The next step will be to merge the privileges table, while preserving
the exiting behaviour in the source3 LSA server.
