 * @brief Test nanokernel FIFO APIs
 *
 * This module tests four basic scenarios with the usage of the following FIFO
 * routines:
 *
 * nano_fiber_fifo_get, nano_fiber_fifo_put
 * nano_task_fifo_get, nano_task_fifo_put
 * nano_isr_fifo_get, nano_isr_fifo_put
 *
 * Scenario #1
 * Task enters items into a queue, starts the fiber and waits for a semaphore.
 * Fiber extracts all items from the queue and enters some items back into
 * the queue.  Fiber gives the semaphore for task to continue.  Once the control
 * is returned back to task, task extracts all items from the queue.

 * Scenario #2
 * Task enters an item into queue2, starts a fiber and extract an item from
 * queue1 once the item is there.  The fiber will extract an item from queue2
 * once the item is there and and enter an item to queue1.  The flow of control
 * goes from task to fiber and so forth.

 * Scenario #3
 * Tests the ISR interfaces.  Function testIsrFifoFromFiber gets an item from
 * the fifo queue in ISR context.  It then enters four items into the queue
 * and finishes execution. Control is returned back to function
 * testTaskFifoGetW which also finished it's execution and returned to main.
 * Finally function testIsrFifoFromTask is run and it gets all data from
 * the queue and puts and gets one last item to the queue.  All these are run
 * in ISR context.
 *
 * Scenario #4:
 * Timeout scenarios with multiple FIFOs and fibers.
