Rte_Enter and Rte_Exit

AUTOSAR provides exclusive areas as a concept for mutual exclusion of runnables. In the software component editor of ASCET, exclusive areas are specified via resources. Reserving a resource is equivalent to entering an exclusive area (Rte_Enter), releasing a resource is equivalent to exiting an exclusive area (Rte_Exit).
