Application layer detection improvements - improve locking of application layer handling, making sure that the flow cannot be freed/cleared when the detection engine is still working with it. - add a check to the app layer detection to make sure that a match function will only inspect an app layer state if it's of the right type. 15 years ago			`uint16_t AppLayerGetProtoFromPacket(Packet *);`
