Kernel changes:

+ Made xTaskNotifyGiveFromISR() its own function, rather than a macro that calls xTaskNotifyFromISR() (minor performance improvement).
+ GCC and Keil Cortex-M4F ports now use vPortRaiseBASEPRI() in place of ulPortRaiseBASEPRI() where the return value is not required (minor performance improvement).

Demo changes:
Change the [very basic] FreeRTOS+UDP SAM4E driver to use task notifications rather than a semaphore (execution time now 55% what it was in FreeRTOS V8.1.2!).
Robustness improvements to IntQueue.c standard demo task.h.
Added the latest standard demo tasks, reg test tasks and int q  tasks to the SAM4E demo.
