Add the macro xSemaphoreTakeFromISR().

Add #error strings if configMAX_SYSCALL_INTERRUPT_PRIORITY is set to 0.
Corrected the prototype of vApplicationStackOverflowHook().
Changed the dimensioning of the buffer declared in prvListTaskWithinSingleList() to make use of the configMAX_TASK_NAME_LEN setting.

+ * Mutex type semaphores (those created using a call to xSemaphoreCreateMutex())
+ * must not be used with this macro.
+ *
+ * This macro can be used from an ISR, however taking a semaphore from an ISR
+ * is not a common operation.  It is likely to only be useful when taking a
+ * counting semaphore when an interrupt is obtaining an object from a resource
+ * pool (when the semaphore count indicates the number of resources available).
+ *
+ * @param xSemaphore A handle to the semaphore being taken.  This is the
+ * handle returned when the semaphore was created.
+ *
+ * @param pxHigherPriorityTaskWoken xSemaphoreTakeFromISR() will set
+ * *pxHigherPriorityTaskWoken to pdTRUE if taking the semaphore caused a task
+ * to unblock, and the unblocked task has a priority higher than the currently
+ * running task.  If xSemaphoreTakeFromISR() sets this value to pdTRUE then
+ * a context switch should be requested before the interrupt is exited.
+ *
+ * @return pdTRUE if the semaphore was successfully taken, otherwise 
+ * pdFALSE
