Added INCLUDE_xSemaphoreGetMutexHolder() default.

Browse Source 
Changed eTaskStateGet() to eTaskGetState() and added #define to ensure backward compatibility.
Added configEXPECTED_IDLE_TIME_BEFORE_SLEEP definition - was previously hard coded to 2.
Slight change to the default CM3 tickless sleep function to allow the idle time to be set to zero in the pre-sleep processing macro.
Changed stack alignment for the FreeRTOS-MPU port to ensure it didn't trigger the assert() in the generic create function.
