I'm continuing to test this branch.  There are some issues with other
parts of Samba that worked due to DB ordering assumptions.  However
overall, I think it is good.

The only other news is that while upgrades will be seamless, downgrades
will require running a script (which I'll write) or modification of the
@INDEXLIST on all the backend DBs.  We don't support a seamless
downgrade.  

I'll do some performance work on it over the weekend.  The previous
tests show a small performance cost (5% or so) on searches, and a bit
performance benefit (%40) on adding users. 

I'll e-mail Tridge/Douglas/Catalyst for permission on a re-licence to
LGPLv3 the binary search macros next week.

I know it is a massive patch set, but some feedback would be helpful.
