The TDB2 decision (ntdb?)

[Rusty Russell]

Here's the summary of what was decided with TDB2: please correct if this
is wrong!

(1) TDB2 will be used in Samba 4.0, introduced during/before beta.
    => If it takes longer than 2 weeks, it won't make the first beta.
    => Rusty will get autoconf tdb2 working.

(2) TDB2 should not be backwards compatible with TDB1.
    => Rusty to remove tdb1 compat code from tdb2.

(3) TDB2 should be a separate library, not a version bump.
    => You will be able to link against both.
    => API names to change from tdb_* to <newname>_*
    => Rusty to poll for a new name: ntdb?

(4) SAMBA 4 will use the TDB2 on-disk format.
    => You can use tdbbackup then tdb2restore to update (offline).

(5) Volker (?) will look at expanding the db_wrap usage so that we can
    potentially interchange tdb1 and tdb2.

Thanks,
Rusty.
PS.  Name suggestions welcome!
