Add a new interceptors for cdbr(3) and cdbw(3) API from NetBSD
Summary: cdb - formats of the constant database. cdbr, cdbr_open, cdbr_open_mem, cdbr_entries, cdbr_get, cdbr_find, cdbr_close - constant database access methods. cdbw_open, cdbw_put, cdbw_put_data, cdbw_put_key, cdbw_stable_seeder, cdbw_output, cdbw_close - creates constant databases. Add a dedicated test for this API.
