+ Fix a few compiler warnings.
+ Add TickType_t specific critical sections so critical sections are not used when accessing the tick count in cases where the access is atomic (32-bit tick count, 32-bit architecture).
+ Optimise Cortex-M4F ports by inlining some critical section macros.
+ Original ports used a #define to set the path to portmacro.h - that method has been obsolete for years and now all the old definitions have been moved into a separate header files called deprecated_definitions.h.
+ Cortex-M port now check the active vector bits against 0xff when determining if a function is called from an interrupt - previously only a subset of the bits (0x1f) were checked.
+ Add in new standard demo/test files TaskNotify.c/h and include the files in the simulator demos.
+ Update trace recorder code, and some demos to use the new version (more to do).
+ Introduce uxTaskPriorityGetFromISR().
+ Minor typo corrections.
+ Update MingW simulator demo to match the MSVC simulator demo.
+ 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.
