The function is called to create a handle to a db table.
On startup, we do not create any of the db handles. Instead it is done on first-use (lazy-initialized) to only create handles to files (db) that we require.
There is one db file per openser table (eg. acc), and they should exist in your DB_PATH (refer to kamctlrc) directory.
This function does _not_ create the underlying binary db tables. Creating the tables MUST be manually performed before openser startup by 'kamdbctl create'
Function returns NULL on error, which will cause openser to exit.
