Update TaskNotify.c to test the condition where a direct to task notification is sent to a suspended task.
Introduce configSTACK_DEPTH_TYPE so the application writer change the type used to specify a stack size from uint16_t to whatever they like.  Defaults to uint16_t if not defined.
Introduce configINITIAL_TICK_COUNT to allow users to start the tick count at something other than 0.  Used for testing, but overflows can be better tested by setting configUSE_16_BIT_TICKS to 1.
Split xQueueGenericReceive() into xQueueReceive(), xQueuePeek() and xQueueSemaphoreTake() as the first step in refactoring xQueueGenericReceive().
Add Cortex-M3 port layer for Code Composer Studio - previously there was only a Cortex-M4F port.
Introduce configPRE_SUPPRESS_TICKS_AND_SLEEP_PROCESSING() to allow applications to prevent portSUPPRESS_TICKS_AND_SLEEP() being called.  Previously the portPRE_SLEEP_PROCESSING() macro could only be used to abort entry into sleep time after clocks had been re-programmed for the distant wake time.
