Carry on working on SAMA5D3 demo:

Browse source 
- Add full interrupt nesting tests.
- Add additional critical section/context switching tests.
- Set interrupt priorities so everything can run at once without any software watchdog errors.
- Re-enable interrupts in each IRQ handler.
- Add in run-time stats.
