From 14230869e6a37526f8a1bdb1fb88f23309b10aef Mon Sep 17 00:00:00 2001

Subject: Remove some db abstraction crap.

These db_open and db_close looked quite useless. And they caused the db
directory to be opened on a simple registering of a database. This is
totally unneeded, this opening can be delayed to when we actually need it.
