Demo application related:

+ Update the RZ IAR project so it targets the RZ RSK rather than custom hardware.
+ Update the RZ ARM/DS-5 project so it targets the RZ RSK rather than custom hardware.
+ Updated RX64M demos to use the new iodefine.h naming.

Cortex-A9 port related:
+ Update IAR, ARM and GCC Cortex-A9 port layers to include a 'task exit error' function which is called if a task attempts to incorrectly exit its implementing function.
+ Moved the instruction which switches into system mode out of the restore context macro, as it is only needed when starting the first task.

Core kernel files related:
+ Ensure there are no references to the mutexes held count when mutexes are excluded from the build.
