Benjamin Walsh ebe62ab63d test_timer: test timeouts/timers in microkernel
Simple tests to verify whether the microkernel timer system works
alongside the nanokernel timeouts and timers system.

Once the timer test is started, the nanokernel fifo timeout test is
started in parallel: each other's timeout times should not be affected
by the other. Also, a fiber is started, pending on a nanokernel timer,
and awakens in the middle of the microkernel timers expiring.

Title: Microkernel low resolution timer test suite

Description:

This test verifies the following low resolution microkernel timer APIs operate
as expected:
  task_timer_alloc (), task_timer_free()
  task_timer_start(), task_timer_restart(), task_timer_stop()
  task_node_tick_delta(), task_node_tick_get_32()

Also verifies the nanokernel timeouts can work alongside the microkernel timers.

Building and Running Project:

This microkernel project outputs to the console.  It can be built and executed
on QEMU as follows:

    make qemu

--------------------------------------------------------------------------------

Troubleshooting:

Problems caused by out-dated project information can be addressed by
issuing one of the following commands then rebuilding the project:

    make clean          # discard results of previous builds
                        # but keep existing configuration info
or
    make pristine       # discard results of previous builds
                        # and restore pre-defined configuration info

--------------------------------------------------------------------------------
