+ Update demos that use FreeRTOS+Trace to work with the latest trace recorder library.

+ 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).
