No, there were too many things we wanted to clean up.  A wrapper would
be possible though (for your point below).

One option was to put the whole tdb1 source code into tdb2 as a fallback
for old tdbs.  Then it's just a question of API changes; we can bump the
soname major number.

Maybe it's less painful to live with the "tdb2" prefix, even though in
five years it's going to look pretty ugly?

I don't really have a strong opinion...
