Introduce
JDBC2 version store type, deprecate JDBC version store …
…type The current `JDBC` version store type uses a lot of columns in the `objs` table, which cause quite some overhead in storage. The new `JDBC2` version store type works like `JDBC`, but uses a single column for all object values and also serializes object-ids as binary values.
