Assigns dynamic message priority according to laxity (time to deadline minus worst case execution time). The message priority is divided into high and low order bit fields. The high order bit field is used for dynamic message priority, which is updated whenever the convert_priority() method is called. The low order bit field is used for static message priority and is left unchanged. The partitioning of the priority value into high and low order bit fields is done according to the arguments passed to the strategy object's constructor.
