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.

*
* It is preferred that the macro xQueueReceive() be used rather than calling
* this function directly.
*
* Receive an item from a queue. The item is received by copy so a buffer of
* adequate size must be provided. The number of bytes copied into the buffer
* was defined when the queue was created.
*
* This function must not be used in an interrupt service routine. See
* xQueueReceiveFromISR for an alternative that can.
*
* @param xQueue The handle to the queue from which the item is to be
* received.
*
* @param pvBuffer Pointer to the buffer into which the received item will
* be copied.
*
* @param xTicksToWait The maximum amount of time the task should block
* waiting for an item to receive should the queue be empty at the time
* of the call. The time is defined in tick periods so the constant
* portTICK_PERIOD_MS should be used to convert to real time if this is required.
* xQueueGenericReceive() will return immediately if the queue is empty and
* xTicksToWait is 0.
*
* @param xJustPeek When set to true, the item received from the queue is not
* actually removed from the queue - meaning a subsequent call to
* xQueueReceive() will return the same item. When set to false, the item
* being received from the queue is also removed from the queue.
*
* @return pdTRUE if an item was successfully received from the queue,
* otherwise pdFALSE.
*
* Example usage:
<pre>
struct AMessage
{
char ucMessageID;
char ucData[ 20 ];
} xMessage;
QueueHandle_t xQueue;
// Task to create a queue and post a value.
void vATask( void *pvParameters )

// Create a queue capable of containing 10 pointers to AMessage structures.
// These should be passed by pointer as they contain a lot of data.
xQueue = xQueueCreate( 10, sizeof( struct AMessage * ) );
if( xQueue == 0 )
{
// Failed to create the queue.
}
// ...
// Send a pointer to a struct AMessage object. Don't block if the
// queue is already full.
