Test the nano_xxx_fifo_wait_timeout() APIs.
First, the task waits with a timeout and times out. Then it wait with a
timeout, but gets the data in time.
Then, multiple timeout tests are done for the fibers, to test the ordering
of queueing/dequeueing when timeout occurs, first on one fifo, then on
multiple fifos.
Finally, multiple fibers pend on one fifo, and they all get the
data in time, except the last one: this tests that the timeout is
recomputed correctly when timeouts are aborted.
NOTE: The timeout APIs test is contained within its own file so that it
is easily reusable by a microkernel test that verifies that nano
timeouts and microkernel timers can coexist.
