Core kernel files:

+ Change how queues are allocated and deleted so only one pvPortMalloc() or vPortFree() is required in place of the previous 2.
+ Where the TCB is allocated in relation to the stack is now dependent on the stack growth direction.  The stack will not grow into the TCB.
+ Introduce the configAPPLICATION_ALLOCATED_HEAP constant to allow the application to provide the array used by heap_4.c as its heap.  This allows the application writer to use qualifiers on the array to, for example, force the memory into faster RAM.

Demo application:
+ Add demo for SAMA5D4 using IAR.
