Using a `db_param_list` `clist` we can preset `SQLITE_OPEN_READONLY` on specific database file, this can be reused for more sqlite specific settings since we probably do not want extand `km_dbase` for db engine specific settings.

This is required when another process is writing to the db

Example: ``modparam("db_sqlite","db_set_readonly","/var/mydb.sqlite")`` You can view, comment on, or merge this pull request online at:
