All related to RL78 GCC demos (which are still a work in progress):
- Abstract out the IO port handling for the LED output so the same code can be used on multiple eval boards.
- Add in the RESTORE_CONTEXT macros.
- Swap to use heap_1.c instead of heap_4.c.
- Add data model macros to FreeRTOSConfig.h (may be removed if only one data model is supported by the compiler).
- Install interrupt handlers.
