Changes to the FreeRTOS code:

Browse source 
+ Introduced xTaskCreateStatic() to allow tasks to be created without any dynamic memory allocation.
+ When a task notification is used to unblock a task from an ISR, but the xHigherPriorityTaskWoken parameter is not used, then pend a context switch to occur during the next tick interrupt.

Demo application changes:
+ Updated TaskNotify.c to test the case where a task is unblocked by an ISR, but does not use its xHigherPriorityTaskWoken parameter.
+ Updated the Win32 MSVC project to test statically allocated tasks being created and deleted.
+ Introduced StaticAllocation.c standard demo task.
