If readwritesplit.c:routeQuery gets a GWBUF whose type is UNDEFINED, then each MySQL packet is extracted from input buffer and passed to new function, route_single_stmt. Each extracted packet is stored in separate GWBUF and added types GWBUF_TYPE_MYSQL and GWBUG_TYPE_SINGLE_STMT which makes it possible to execute session commands and process reply packets properly. Code nedes still cleaning but this is for testing atm.
