BerkeleyDB Blockchain building, not working yet

Everything except actually *using* BlockchainBDB is wired up, but the db
itself is not yet working.  Some error about user mem not large enough.
I think I know what this error means, but I can't determine the cause.

Notes: BerkeleyDB does not allow 0-indexing in its recno type databases,
  so block numbers *in the database* will be 1-indexed.  Modifications
  to indexing have been made as needed.
