Preparing for maintenance release:
Kernel source changes:
- Added xTaskNotifyStateClear() API function.
- Added the GCC Cortex-R port (existed for a while) into the main download.
- Improved the IAR RL78 port's handling of different memory model combinations.
- Removed some compiler warnings in heap_5.c.
Demo app changes:
- Added example use of xTaskNotifyStateClear() to the TaskNotify standard demo tasks.
